To project the modis grid you can use the project tool in the data management / projections and transformations tool box. Or even easier, you can just export the layer out of ArcMap. If the coordinate system of the data frame is "Lo19", check "use coord sys of dataframe". A word of warning. That path to your data is rather convoluted and has spaces and other funny stuff in it like "@". Rather make the path to your data a bit simpler and do not have any funny stuff in the path. Some tools fail when given paths like that. Also the path says ...filegeodatabases, but the actual file is a shapefile???. Why not make a file geodb and put the data in that. You may want to redefine the GCS / Datum of the Modis data. I have to presume that this should be GCS_WGS84. In ArcCatalog, navigate to the file, right click to get the properties page, right click the coord sys definition and select "Copy & Modify", make sure you give it a meaningful name and change the GCS to WGS84. ...

Sorry, but where are the red square polygons coming from? Are they the 1km(?) pixel outlines from the modis data? I can't get much info from noaa on the details of the CS for modis. If you are projecting from Modis CS to "Lo19", you may want to densify those polygons a bit. And you need to specify a bit better the actual projection of the modis data. Is that poorly defined CS exactly as it was when downloaded? ... View more

When you say "LO 19", you probably mean a normal Transverse Mercator centered on Long 19E. Based on Hart94. Hart94 is functionally equivalent to WGS84 so there should be no "transformation issues" between the satellite data and your crop data. Could you post some snapshots of the properties page - CS and extents for both please. ... View more

If those original coords are utm, then it is about 6 or 7 zones to the right of the zone you are using. Might be considerable distortion in your data. ... View more

Your data is indeed in HDD MM.ss (degrees, minutes and decimal minutes), so it is a text string and should be imported as such. So I would mess with the format. Just need to calculate the decimal degrees from this. This could be done in the spreadsheet using a bit of string manipulation or try to use : Convert Coordinate Notation—Help | ArcGIS Desktop  ...

And, if the XY coordinates you are talking about are columns in the attribute table of the features, than no, these attributes are not auto-magically updated when the feature is projected to a new coordinate system.

At first glance, I thought these were GCS (geographic) coordinates, but that doesn't look correct. New netcdf file extent : Top : 188,5 Bottom: 0,5 Right: 177,5 Left: 0,5‍‍‍‍‍‍ Bottom left is 0.5, 0.5. Top right is 177.5, 188.5 Doesn't look like anything to me. Are you sure this data is actually georeferenced to anything. And, those numbers on your original data don't look anything like i would expect from UTM. Have you actually looked at this data with some other background info to confirm that it is where you think it is? ... View more
