Hi Lex,

Here is the post. If you still have problem, you can send me a sample image of both data sets. I haven't work with Europa or Io data before, but I can take a look. Thanks,

June

No-data area will not change the line and sample value of each pixel in the data. So the data will still start from (1,1) for the top-left corner. All you need is just ignore those no-data pixels in your calculation without changing the line and sample values.

One more finding is if using the function of “y = (1 - L0 - Line) * Scale” in line 128 of ‘DSMAP.CAT’ file, y value will always be negative with current label value input, which doesn’t match with the real y value in the data. It looks to me this equation could be changed to “y = ( L0 – Line-1) * Scale”.

You can try LINE_PROJECTION_OFFSET = 4476. This value is just my guess, may not be correct.

I have contacted with the data provider. I will post the final solution here when I hear anything back from the data provider’s.

Hi Ayushman,

Two things here. In your code, you looped around all the pixels. Please don’t include the nodata area in your calculation.

The LINE_PROJECTION_OFFSET value in the label doesn’t match with the value of CENTER_LATITUDE. Need to check with the data provider to see what the value used in their processing pipelines.

Thanks,

June

Hi Ayushman,  

Attached is the screen capture of the LROC RDR (orange color, NAC_ROI_VIKRAM__LOC_P708S0237_5M.TIF) overlain on a WAC mosaic near the South Pole area together with its spatial reference information. The feature matches well. If everything is correct in the book, it looks to me equation 20-15 is a better fit for this case. Have you checked other parameters or steps in your calculation? If you can send me your code and your original value input for the calculation, I can take a further look. Thanks,

June

Hi Ayushman,

Question 1-> It looks to me C = 2* ARCTAN[P/(2*Rp)] is correct, when compared this with the equation (21-15) in book page 159 of the book “Snyder, J. P. (1987). Map Projections: A Working Manual. U.S. Geological Survey Professional Paper 1395. Washington, DC: United States Government Printing Office.” Please let me know if this is not correct to your test.

Question 2-> Please use the value in the attached label. The sentence written in the DSMAP.CAT is more like a general case.

Thanks,

June

Hi Ayushman,

To get the lat&lon for each pixel of the LROC map projected RDRs, please read the ‘DSMAP.CAT’ at https://pds.lroc.asu.edu/data/LRO-L-LROC-5-RDR-V1.0/LROLRC_2001/CATALOG/, which gives the equations and steps on how to convert image array coordinates (Sample, Line) to map coordinates (x, y), and then from map coordinates (x, y) to planetocentric coordinates (Lat, Lon) for different kind of projections. All the parameters needed for the calculation could be find in the attached label of this product. Please let me know if you need more information. Thanks,

June

 

 

 

Hi Ayushman,
Sorry, these are LROC NAC CDR data products. They are not map projected, but you can still use Arcmap and Gdal to read the data. I confused them with the LROC RDR data in your other post at https://geoweb.rsl.wustl.edu/community/index.php?/topic/2804-details-needed-for-lroc-nac-mosaic-img-file/&tab=comments#comment-4594. I will keep a post there on how to get the lat&lon for each pixel of the LROC map projected RDRs.

In the index table under INDEX directory of the LROC CDR volumes, e.g., https://pds.lroc.asu.edu/data/LRO-L-LROC-3-CDR-V1.0/LROLRC_10**/INDEX/, you will find the lat&lon coordinates of the center point and 4 corner points. If you want to get the lat&lon for each pixel in the image, you will probably need to try the NAIF SPICE tools https://naif.jpl.nasa.gov/naif/toolkit.html or USGS ISIS https://isis.astrogeology.usgs.gov/index.html to see if they have function for this.  

Thanks,

June

October 6th, 2020 - New MEX OMEGA EDR Data Loaded into ODE
- Updated MEX OMEGA EDR data products for extended mission 7 released through December 22nd, 2019 (Orbit 20196).

Hi Ayushman,

You can use gdal_translate command from gdal tool to translate the img data into a Geotiff, and use this Geotiff in any GIS tools.

Arcmap can read the PDS IMG data directly with all its spatial reference information. The version I used here is an old one 10.2.2. Higher version should also work.

June

Hi Ayushman,

This LROC IMG data has an attached label. You can view the label content with UltraEdit or a Nodepad tool. From the link you gave above, you can also download the Geotiff image from Extra Downloads box. When adding this Geotiff in Arcmap and moving you mouse on the image, you can see the coordinates of each pixel. Because this product is in Polar Stereographic projection, the default coordinates display is in meters. You can change the map setting to view the coordinates in degrees. Since this data including NoData, the red part as shown below, the westernmost longitude is not  the left side of the mosaic and the maximum latitude doesn't correspond to the top of mosaic.

Please let me know if you need more help. Thanks,

June
