.img files corrupt

Sun, 24 Jan 2016 21:41:04 +0000

I am currently working on a school project and am trying to download topographical images of Mars at high resolution. I am still trying to figure everything out on the sites and learn how to use the Mars Orbital Data Explorer. However, I am running into the issues of my downloaded files being corrupt for some reason. I am following the instructions from the User Manual the best I can, but it does not seem to be working. I add the items I want to my cart, and when I receive the email confirmation, I download them using FileZilla. When I try to open the .img files though, I get an error message saying the disc image is corrupt. I have also attempted to convert those files into PNGs using the IMG2PNG tool that was recommended on this page http://www.planetary.org/explore/space-topics/space-imaging/data.html?referrer=https://www.google.com/?referrer=http://www.planetary.org/explore/space-topics/space-imaging/data.html. However, when I do the conversion, I just get a black image (presumably because the file is corrupt).

Basically what I want to do is to create heightmaps (bitmaps) of Mars based on the data collected by NASA on various missions. I cannot seem to figure this out though. I plan to use the generated heightmaps to create partial landscapes in Unreal Engine, which happens to want them in PNG format, so I thought this would be perfect. The issue is the downloads don't seem to work, and I would eventually need grayscale images anyhow (which I also can't seem to find on the site, though I am unsure how to specifically do that).

Hopefully I have provided enough information here. If anyone has any suggestions or needs more information, please ask.

Thank you.

Smart Sorting of Data Query Results

Sat, 23 Feb 2019 16:49:49 +0000

Hi,

I was trying to search for LROC Wide Angle Camera Color data: "Calibrated Data Record Wide Angle Camera - Color (CDRWAC)" for a region of interest. The search returned 947 files. I tried searching for ways to either filter out data or sort it in a way that I don't have to go through each record. However, other than basic options such as by Mission, Instrument, Product ID and Observation Parameters, there were not a whole lot of options.

I wish to share a few suggestions that I could think of, that might help:

a) Sorting by coverage: While there were some data covering very small parts of the region of interest (ROI), there were others covering large parts of ROI.

b) Sorting by spatial resolution: I could not locate if all the data were acquired with same spatial resolution. If not, that could be another possibility.

c) Sorting by Data Size

d) Artificial Intelligence (AI) assisted solutions: Not sure if it sounds far fetched but there could be simple routines that can be prepared to offer an 'optimized download solution' if the user desires. For example, in my case, an algorithm could be implemented using 'data with minimum size and maximum coverage of ROI' or 'data with highest resolution for ROI' or 'data clustered on the basis of same resolution and geographic proximity to provide set of data with seamless coverage'.

Lastly, at conferences like Lunar and Planetary Science Conference (LPSC), it would be great to have 30-45 min workshops at your booth on:

a) Solutions to most commonly asked questions by planetary community (viz. opening PDS data into ENVI)

b) New Data products from Recent Missions

c) Useful tools for handling planetary data

Hope to hear back your thoughts.

Best Wishes

Opening file formats

Tue, 30 Oct 2018 01:21:57 +0000

Hi, I downloaded the image files I wanted, but I'm having trouble opening them. The IMG files are supposed to be mounted, but they are always said to be "damaged". Is there a section describing how to deal with all the formats found in ODE?

Thank you.

Chandrayaan-1 MINI-RF raw PDR data format

Sun, 12 Feb 2017 12:41:25 +0000

This is regarding Mini-RF Forerunner NASA instrument onboard Chandrayaan-1. I am trying to decode the Raw Packetized Data Record (PDR) in CCSDS format. I am able to decode all the auxiliary information. But when I am trying to decode Science data (echo data) in the packet, I am not able to find information regarding complex samples. Nothing regarding the complex sample (individual I & Q) and BAQ is mentioned in data format (PDS Data Product Software Interface Specification: MRF-4008, page number 11). In particular,

ftp://pds-geosciences.wustl.edu/lunar/ch1-orb-l-mrffr-1-pdr-v1/ch1mrf_0xxx/document/dp_sis/mrffr_dp_sis.pdf is the document i am referring to. Any help in this regard will be appreciated.

THEMIS IR/VIS footprint shapefiles

Hi,

I was searching for the latest shapefile footprints of THEMIS IR and VIS data. Where can I find these?

Thanks in advance,

HiRISE viewer HiView and ArcGIS

Tue, 06 Dec 2011 20:16:04 +0000

Hi,

I found an easy way to use the new HiRISE HiView viewer within ArcGIS 10. It is explained on my blog: http://leukvoorj.iivision.com/?p=578

For everything to work I added a column JPIPURL to your HiRISE footprint shapefile. I was wondering if you could maybe add this to your shapefile?

Thanks in advance,

little HiRISE shapefile error

Thu, 24 Nov 2011 15:36:43 +0000

Hi,

Just want to let you know that I found a small geometry error in the polygon feature with FID=22954 in http://ode.rsl.wustl.edu/mars/datafiles/derived_products/coverageshapefiles/mars/mro/hirise/rdrv11/mars_mro_hirise_rdrv11_c0a.zip (one part of the image PSP_008342_2655_RED). Visual inspection in ArcGIS showed it was not a correct polygon.

Cheers, Jelmer
