Shapes are increasingly distorted away from the central meridian and near the poles. So: X coordinate of lower-left corner = -20015109.354 + horizontal tile number * tile width = -20015109.354 + 17 * 1111950.5196666666 = -1111950.5196666643 m, Y coordinate of lower-left corner = -10007554.677 + (17 - vertical tile number) * tile height = -10007554.677 + (17 - 3) * 1111950.5196666666 = 5559752.5983333346 m. If you search through the HDF file header carefully, you can discover the horizontal and vertical tile numbers in it as well. But I am not an expert in datums and projections, so I am hesitant to conclude anything here. Active 2 years, 6 months ago. Like the stereographic projection and gnomonic projection, orthographic projection is a perspective (or azimuthal) projection, in which the sphere is projected onto a tangent plane or secant plane. rev 2021.2.5.38499, The best answers are voted up and rise to the top, Geographic Information Systems Stack Exchange works best with JavaScript enabled, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Learn more about hiring developers or posting ads with us.

We can assume this because only one radius is provided, 6371007.181000 m. This value appears to be the authalic radius for WGS 84; if you compute the authalic radius using the a and b parameters for WGS 84, you get this value. The boundary meridians bulge outward excessively producing considerable shape distortion near the map outline. This expression extracts the characters of the HDF name up to the first dot, with a maximum of 13 characters so the name will be a valid ArcInfo Binary Grid name. In the UK, can a landlord/agent add new tenants to a joint tenancy agreement without the consent of the current tenants? The use of orthographic projection in cartography dates back to antiquity. I do not know which organization defines the versions and projections. I've worked with big raster datasets a lot recently, and while I mostly use R, for converting to a new projection I found that QGIS is much more efficient. Example of Dutch grid (RD / AME-7): 192309 325406 (x y) To geolocate a given tile properly, we need to know precise values for the tile's cell size and the coordinates of its lower-left corner. When I tried this, the shoreline was not aligned with the MODIS data, as show below. The MOD10A1 daily product is gridded in equal area tiles. Protective equipment of medieval firefighters? Geographic coordinates converter. It is typically stated that this projection is area-preserving, meaning that while shapes and angles may be distorted, the ratio of the area of any region calculated in the projected coordinates to the area measured on the surface of the globe … It may be the last option available, and you may have to scroll down to see it. The level of zoom is different in each image. A geographic coordinate system is often desired when overlapping a layer with a web based mapping service such as Google, Bing or OpenStreetMap (even though these web based services end up projecting to a projected coordinate system–most likely a Web Mercator projection). Then I created an empty raster with world extent and define a projection. Visit the Trac open source project athttp://trac.edgewall.org/, MOD11A1.A2006034.h17v03.005.2008074151903.hdf, MOD11A1.A2008006.h16v07.005.2008007232041.hdf, MOD11A1.A2008004.h12v04.005.2008006021326.hdf, MOD11A1.A2008018.h13v13.005.2008019174742.hdf, MOD11A1.A2008004.h28v12.005.2008006022646.hdf, Find HDFs and Convert SDS to ArcGIS Rasters, Convert SDS in HDFs Listed in Table To ArcGIS Rasters. Finally, the data are neither conformal, perspective, nor equidistant (USGS 2000). ee.Terrain.gradient or ee.Terrain.slope). Some providers of MODIS data distribute HDFs containing Level 3 grids in sinusoidal projections. First, open the Create Custom Geographic Transformation and fill in the four inputs as follows: The filled-in tool should look like this: Now we want to project the WGS 84 geographic data to the MODIS sinusoidal projection. I do not know the source of this error. Learn about equation-based transformation methods. Do you know other option for conversion from ellipsoide to WGS84? From here. By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy. The tool performs three things as part of this process: It unprojects the data into geographic coordinates (latitude and longitude). Most Coverage tools, among them Build and Clean, assume you have a planar, two-dimensional dataset. Examples of pseudocylindrical projections include: Sinusoidal, which was the first pseudocylindrical projection developed. https://stackoverflow.com/questions/36772341/reading-hdf-files-into-r-and-converting-them-to-geotiff-rasters, But I found that the product is in sinusoidal projection, and I want to convert it to WGS84. I am interested by MODIS product. So my advice would be to try to open your raster in QGIS and use "Raster"->"Projections"->"Warp (Reproject)". Now that we have converted a land surface temperature image to ArcInfo Binary Grid format, we want to make a map that includes this image and other data, such as the GSHHS shoreline. It became the standard map projection for navigation because it is unique in representing north as up and south as down everywhere while preserving local directions and shapes. In the Layers tab above, we saw that the scale factor was 0.2 (this is also present in the HDF header), so we can use this expression: We also check the Build pyramids box so the tool will save us from doing this later. This is what I've tried and seemed to work: What happens if a prosecutor refuses to file charges? The cell size corresponds to the True Scale listed in NSIDC's Table 2. It takes a lot of times, and R crash (I obtain a message R session aborted). Sign up to join this community. What software should I buy to have a macOS VM on my Linux machine? It is hard to find information on this projection. It only takes a minute to sign up. At the time of this writing, MGET was not included in that list yet it can be use to convert the data. Coordinate conversion is composed of a number of different types of conversion: format change of geographic coordinates, conversion of coordinate systems, or transformation to different … This makes ArcMap pretty slow. Geographic Information Systems Stack Exchange is a question and answer site for cartographers, geographers and GIS professionals. The black is the shoreline produced with LONGITUDE_ROTATION, the red is it produced with GEOCENTRIC_TRANSLATION. In this example, we want to convert land surface temperature (LST) data from LP DAAC's MODIS/Terra Land Surface Temperature & Emissivity Daily L3 Global 1km dataset (MOD11A1) to ArcInfo Binary Grid format. To convert the data to the “ geographic” projection, from the Toolbox select Raster Management | Reproject Raster. It seems that all of them assume some parameters like pixel size or xy origins but I need to get all of the parameters from the raster itself, it suppose to be as generic as possible, the only constant thing is the output coordinate system which is wgs84 (EPSG=4326). But the distance 1200 km and 500 km are really just rough approximations. First, we open MGET's Convert SDS in HDF to ArcGIS Raster tool, choose the HDF to convert and, specify an output raster. For example from WGS 1984 to Dutch grid or from UTM to Ordnance Survey Great Britain 1936. Starting with Version 4, data providers began using a "Sinusoidal Grid" projection. Because you loaded the MODIS image first, the data frame uses its coordinate system. In some cases, it appears that land extends beyond the shoreline (e.g. Smaller regions using the interrupted form exhibit less distortion than the uninterrupted sinusoidal projection of the world. This effectively shows the land mask used for this dataset. I have never seen ESRI documentation on the various transformation methods. It depicts a hemisphere of … Many MODIS data products are organized in a tile grid based on a sinusoidal projection. It is an equal-area projection designed for small-scale maps. Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. I do not fully understand why this method works. Finally, we need to set Execute map algebra expression to an expression that will scale the integers from the HDF file to the actual floating point values. LP DAAC offers the MODIS Reprojection Tool, which can convert them to GeoTIFFs, and also provides a list of other tools. The scale along all parallels and the central meridian of the projection is accurate. This article is about converting the GK (Gauss-Krüger) coordinates into WGS 84 (Latitude/Longitude) Background: In cartography, the term Gauss–Krüger Geographic coordinate system is named after Carl Friedrich Gauss (1777-1855) and Johann Heinrich Louis Krüger. As you can see, the land mask lines roughly with the GSHHS shoreline, but not exactly. This projection is based on a sphere rather than an ellipsoid. At the time of this writing, these data were available from NASA's WIST and also LP DAAC's Data Pool. The output in ArcMap looks like this. I coded the image so that the value 3 was blue and all other values were green. Each tile consists of a 1200 km by 1200 km data array, which corresponds to 2400 by 2400 cells at 500 m resolution. It could be that the projection procedure used by ESRI is different than that used by the MODIS data provider. New England). We obtained the GSHHS shoreline by downloading the GSHHS 2.0 shapefiles available on the GSHHS website. This example only applies to data in that projection. All geographic datasets have a coordinate system that is used throughout ArcGIS to display, measure, and transform geographic data. It is a particular set of transverse Mercator projections (map projections) used in narrow zones in … Now, under Post-conversion processing, we need to fill in Define coordinate system with a custom sinusoidal projection based on the MODIS 6371007.181 m sphere: After filling this in as shown, click Finish, Finish, OK to get back to the Convert SDS in HDF to ArcGIS Raster tool. TWCC is compatible with most environments (Mac, Linux, … Projections. In geodesy, conversion among different geographic coordinate systems is made necessary by the different geographic coordinate systems in use across the world and over time. A downside of this approach is that the translation from the WGS 84 ellipsoid to the MODIS sphere happens on the fly, as you pan and zoom the map. Why does adding one character to my MySQL password lock me out? I do know that the forum thread's suggestion of using GEOCENTRIC_TRANSLATION and leaving the parameters set to zero, rather than using LONGITUDE_ROTATION (which has no parameters), does not seem to work. The tool goes through the table and performs one conversion for each row. Mathematical calculations are used to convert the coordinate system used on the curved surface of earth to one for a flat surface. The tool would report an error saying that multiple input files produced the same raster name. Thanks for contributing an answer to Geographic Information Systems Stack Exchange! There are some hints about how to do it in an ESRI forum thread. Attempting to remove extra “edges” from truncated icosahedron lead to excessively global consequences. Projection Wizard is a web application that helps cartographers select an appropriate projection for their map. Powered by Trac 0.12.5 Collignon projection, … This is the python source. It could be the GSHHS data is not georectified properly (although I doubt that, after working with the GSHHS data for a few years). Sign up to join this community. This tile is horizontal number 17, vertical number 3. To do this, weneed to know the horizontal and vertical number of the tile. construct a .DBF table with Microsoft Excel, construct a .CSV file with a text editor, etc.). The original raster is here: > ras_sinu class : RasterLayer dimensions : 33600, 86400, 2903040000 (nrow, ncol, ncell) resolution : 463.3127, 463.3127 (x, y) extent : -20015109, 20015109, -6671703, 8895604 (xmin, xmax, ymin, ymax) coord. Is it unethical to accidentally benefit from online material in a take-home exam? import math class GlobalMercator(object): def __init__(self, tileSize=256): "Initialize the TMS … The SDS name is available in the HDF file header (see the main HDF example for how to extract and interpret this) but it is also available on LP DAAC's web page for this dataset, under the Layers tab, along with other useful information: We can calculate the X and Y coordinates of the lower left corner of the tile using the formulas I listed above. I use five files in this example: This example resembles the main MGET HDF conversion example. Faster if you have mutlpile rasters to convert, and faster than raster package. If you have 9.1, you can probably use the second method below. This opens the Reproject Raster dialog window. Some methods convert the geographic coordinates to geocentric (X,Y,Z) coordinates, transform the X,Y,Z coordinates, and convert the new values back to geographic coordinates. Other methods, such as NADCON and NTv2, use a grid of differences and convert … When you obtain GIS data, it often needs to be transformed or projected. For best results, it is essential that you calculate it yourself and use as accurate a value as possible! Please edit your question and show us what went wrong. According to the LP DAAC page, the value 3 (binary 11) indicates that the "LST [was] not produced primarily due to reasons other than cloud". I tried with only one year, and when it works (after restarting R session after loading the raster for example) I have a similar issue to this person, where I have only data in the "northern" hemisphere : Converting sinusoidal to WGS - MODIS TIFF file too big with R, https://stackoverflow.com/questions/36772341/reading-hdf-files-into-r-and-converting-them-to-geotiff-rasters, https://lpdaac.usgs.gov/products/mod17a3hgfv006/, Sequencing your DNA with a USB dongle and open source code, Podcast 310: Fix-Server, and other useful command line utilities, Opt-in alpha test for a new Stacks editor, Visual design changes to the review queues, Layers in QGIS that Should Align Don't (but do in FME), QGIS 3.10 not recognising projection information from raster created using GDAL, QGIS 3.12 issues unknown CRS on vector shapefile layer, Etiquette for replying to eager HR acting as intermediary. : +proj=sinu +lon_0=0 … Geographic Information Systems Stack Exchange is a question and answer site for cartographers, geographers and GIS professionals. Asking for help, clarification, or responding to other answers. Finally, if you have ArcGIS 9.2 or later, you can use ArcGIS's own batch processing capability. Thanks to Lena, I maybe found a R solution with the gdalUtils, You can directly reproject it with the following code, where you specify your raster file, the destination file (where outdire is the path where I want to put the results), with the projection of the MODIS product and the desire projection (here WGS84). Define sinusoidal projection. Can a Spell with “Self” Range be Cast by Homunculus Servant? MGET includes two batch-conversion tools. The area of any region is true. In order to … sinusoidal projection n. An equal-area map projection in which parallels and the prime meridian are straight lines and the other meridians are increasingly... Sinusoidal projection - … The possibility to add user-defined systems and the use of an interactive map make it flexible. Viewed 17k times 4. To get this component, you can modify the default expression to this: os.path.join(outputWorkspace, os.path.dirname(inputFile[len(directoryToSearch)+1:]), os.path.basename(inputFile).split(u'.')[1][:13]). The point of perspective for the orthographic projection is at infinite distance. Local angles are correct along the central meridian and the equator but distorted elsewhere. Projecting data. Learn more about geographic coordinates While there is not a way in the script to define a UTM projection that automatically chooses the most appropriate zone for the loaded data, you can do this in the File->Batch Convert/Reproject menu command. I have tested with R, but files is maybe too big (too many cells because it is a high resolution, more details of the product here https://lpdaac.usgs.gov/products/mod17a3hgfv006/). Sinusoidal Projection. (I did read somewhere that the differences between the two are negligible, but I can't find that web page.). Projection method. These include the Geocentric Translation, Molodensky, and Coordinate Frame methods. From that thread and some experimentation, I know of two methods. I've found a source code in python and tried to port it into C#. If you have not converted HDFs with MGET before, you may want to review that example before proceeding. The sinusoidal projection is a pseudocylindrical equal-area projection displaying all parallels and the central meridian at true scale. You can view and edit the … Prerequisite Skills This booklet assumes that you have completed the … The second component of the HDF name, which contains the date of the image, may be more unique, resulting in names like A2006034. According to various websites, MODIS data providers used an "Integerized Sinusoidal Grid" projection up through Version 3 (V3) of MODIS data. Ask Question Asked 8 years, 3 months ago. ref. Add ribbon of most used commands-How it could be implemented? If anyone provides a more detailed explanation on the forum thread (or just emails me, jason.roberts@duke.edu), I will add it here. in the Africa and Patagonia image). Did the Tiger Game.Com include any hardware accelerated graphics? You can then save your re-projected raster, load it into R and keep going from there.. That page provides the following description: In the sinusoidal projection, areas on the data grids are proportional to the same areas on the Earth, and distances are correct along all parallels and the central meridian. Some comments in the ESRI forum thread indicate that the goal of this exercise was to create a "null transformation" and rely on ArcGIS's capability of automatically translating coordinates between ellipsoids and spheres. In these images, I zoomed in on recognizable features to see how well they came out. I am working with theMOD15A2. Hello! I've read this solution , and this , and this , and others. Area. This method uses an ArcGIS geoprocessing tool called Create Custom Geographic Transformation, which exists in ArcGIS 9.2 and later. For faster performance, use Method 1 above. Converting these data to ArcGIS-compatible formats can be tricky. The Sinusoidal Projection is a coordinate transform often used to map geographical coordinates on to a flat surface in order to generate a map. In any case, if you need results accurate to the 1 km resolution of this data, I encourage you to check the georectification of your images using a high resolution dataset that you trust and consult the original data provider about any apparent problems. refvecToGeoRasterReference — Convert a referencing vector to a geographic raster reference object. The MODIS land products are produced at 4 resolutions (250m, 500m, 1km, and 0.05 degree), and in 3 projections (Sinusoidal, Lambert Azimuthal Equal-Area, and Geographic). The sinusoidal projection is a pseudocylindrical equal-area map projection. This will presumably work on ArcGIS 9.1 and earlier, but I haven't tested it. Since there is no perfect way to transpose a curved surface to a flat surface without some … The geographic coordinates, however, showed very low accuracy (65.3 percent) when sample datasets were reprojected to the UTM projection, while the sinusoidal projection showed the highest accuracy (98.4 percent). Making statements based on opinion; back them up with references or personal experience. On the map, as in reality, the length of each parallel is proportional to the cosine of the latitude. Enter the coordinates and choose the current datum of the coordinates and to which datum they need to be converted. File:Sinusoidal projection SW.jpg to appear as POTD. NSIDC describes these data as a 36 by 18 array of 1200 km by 1200 km tiles, where each tile is 2400 by 2400 cells, and the cells are 500 m by 500 m. Each HDF file contains one tile. This makes sense because both the shoreline and the MODIS data presumably use the same WGS 1984 datum. For Custom Geographic Transformation, select LONGITUDE_ROTATION. This tool converts coordinates from one datum to another datum. The crux of this problem is understanding the MODIS sinusoidal projection and representing it properly in ArcGIS. will not work. The filled-in tool should look like this: Now we want to project the WGS 84 geographic data to the MODIS sinusoidal projection. The following image shows tile locations for MOD10A1 V005 data in a sinusoidal projection. Note that NoData values are set to gray. Also called Babinet, elliptical, homolographic, or homalographic, Carl B. Mollweide created this pseudo cylindrical projection in 1805. Below, we show how to use MGET's HDF conversion tools to convert land surface temperature (LST) data from LP DAAC's MODIS/Terra Land Surface Temperature & Emissivity Daily L3 Global 1km dataset (MOD11A1) to ArcInfo Binary Grid format. Anybody can ask a question Anybody can answer The best answers are voted up and rise to the top Home Questions Tags Users Unanswered Converting sinusoidal to … I suspect it is some group at NASA Goddard Space Flight Center (GSFC). var proj = ee.Projection(...); var output = collection.reduce(...).reproject(proj); A few cases that require a fixed projection include: Computing gradients (e.g. Meridians are represented by sinusoidal curves except for the central meridian, and parallels are represented by straight lines. What's to stop the House majority party from voting to expel every member of the House minority party from committees? In this example, we will use the British Isles HDF and create a raster called nw_europe.
