A very small sample of common products are listed below. Open the Project tool and populate it as follows: For Input Dataset or Feature Class, select the WGS 84 geographic data. 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. This will presumably work on ArcGIS 9.1 and earlier, but I haven't tested it. Once you have downloaded the MCD12Q1 data for the MODIS tile(s) covering your study area you can open the file in ArcGIS. Not all projection software recognizes the "semi_major" and "semi_minor" arguments to Sinusoidal … The second component of the HDF name, which contains the date of the image, may be more unique, resulting in names like A2006034. I never tried though. You should consider reprojecting the raster dataset to the Geographic WGS84 coordinate system. ranghetti closed this in … Shapes are increasingly distorted away from the central meridian and near the poles. But I found that the product is in sinusoidal projection, and I want to convert it to WGS84. The tile coordinate system starts at (0,0) (horizontal tile number, vertical tile number) in the upper left corner and proceeds right (horizontal) and downward (vertical). Python code. 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. Now we can populate all of the mandatory fields of the tool, along with the NODATA Value, which we looked up in the Layers tab above. You can find an online calculator here, that will convert from tiles to latitude and longitude coordinates.This tutorial will demonstrate how to perform this conversion in Python. 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. Note: The address' attributes are normalized to US feature names and can be mapped to the local feature levels (for example State matches "Bundesland" in Germany). Specific parameters are listed in Table 2: Table 2. Active today. This projection is based on a sphere rather than an ellipsoid. Now we want to project the WGS 84 geographic data to the MODIS sinusoidal projection. I do not fully understand why this method works. So, in essence, this MODIS sinusoidal projection uses a sphere that has the same area as the WGS 84 ellipsoid. 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, 0° longitude, oriented vertically at top. SpatialReference modis_sinu = osr. Yale. The best I have found is an ​NSIDC web page that describes their MODIS/Terra Snow Cover Daily L3 Global 500m Grid, Version 5 product. It could be the GSHHS data is not georectified properly (although I doubt that, after working with the GSHHS data for a few years). MODIS Sinusoidal . To a normal ellipsoid/WGS84 one that is compatible with other datasets I'm analyzing. Once you have determined the parameters needed to convert one tile, you can easily convert a batch of tiles using these values. 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.
