MSL ArcGIS Map Version 1 January 2011 An ArcGIS map was generated for each candidate Mars Science Laboratory (MSL) landing site. The maps and the data layers included are in an equirectangular projection centered at 0 degree longitude and the center latitude of each landing ellipse. Most of the data used in the map including both standard PDS products and special products can be accessed through MSL Orbital Data Explorer (ODE) website at the following link. http://odetest.rsl.wustl.edu/ode_landing_site/indexProductSearch.aspx. -------------- -------------- Data Sources Footprint shape files: http://ode.rsl.wustl.edu/mars/indextools.aspx Shaded relief maps and landing ellipses from Jet Propulsion Laboratory (JPL). CRISM IR/VNIR browse images: http://crism.jhuapl.edu/msl_landing_sites/#label1 THEMIS mosaics: http://astrogeology.usgs.gov/Projects/MSL/ http://themis.asu.edu/landingsites/ http://webgis.wr.usgs.gov/msl/ -------------- -------------- Map File Names Eberswalde_crater_maps.zip Gale_crater_maps.zip Holden_crater_fan.zip Mawrth_Vallis_site2_maps.zip ----Projection---- All datasets are formatted as Projection: Equirectangular Central Meridian (clon) = 0 Standard Parallel (clat) = center latitude of each landing ellipse at the candidate MSL landing sites (see delow) Center of each landing ellipse for candidate MSL landing sites [1] Landing Site Lat(°) Lon[0, 360](°) Eberswalde Crater -23.86 326.73 Gale Crater -4.49 137.42 Holden Crater -26.37 325.1 Mawrth Vallis(2) 24.01 341.03 Coordinates System = Planetocentric (Areocentric) relative to IAU2000 reference frame Positive Longitude Direction = East Major Axis = 3396190.0 m Minor Axis = 3396190.0 m ----Footprint Shape Files---- Footprints were added for: MRO HiRISE red and color images, MRO CRISM TRDR data, and MRO CTX EDR data covering the four candidate MSL landing sites. More shape files could be added upon user request. The landing ellipse layers use the revised parameters listed below. The maps will be updated when the new ellipse parameters are released in 2011. Center of each landing ellipse for candidate MSL landing sites [2] Landing Site Lat(°) Lon[0, 360](°) Eberswalde Crater -23.8953 326.7426 Gale Crater -4.4868 137.4239 Holden Crater -26.4007 325.1615 Mawrth Vallis(2) 23.9883 341.0399 *notes: All the coordinates in this file are areocentric and relative to IAU2000 reference frame. ----Raster Images---- CRISM IR/VNIR browse images were downloaded from CRISM team website, http://crism.jhuapl.edu/msl_landing_sites/browse/Holden_Crater_Fan/index.php. Map projection parameters were read from the image label and added into the *.tfw world file. All of the CRISM browse data are in equirectangular projection centered at 0 longitude and the center latitude of each old landing ellipse [1]. Original crism images are saved in png format. They were output to tif format images because ArcGIS has a bug in 9.3.1 version. ArcGIS 9.3.1 can not read the correct map projection information from the png format raster images, but it works well with the tif format images. The basemap includes THEMIS daytime IR, night-time IR, Qualitative Thermal Inertia, VIS data and MGS MOLA/MEX HRSC shaded relief maps. The original THEMIS images were created by Robin Fergason and the THEMIS Team. These images were in Equidistant Cylindrical (Simple Cylindrical) projection centered at 180 longitude and 0 latitude. The THEMIS data were re-projected into the same coordinate systems as the CRISM IR/VNIR browse images. After re-projection, the THEMIS data were also moved horizontally (x and y direction) in order to match with the features in the CRISM IR/VNIR images. Two shaded relief maps were created at JPL. One was generated using the MEX HRSC DTM (~75m/pixel) with its 12m/pixel visible orthophoto draped over it. The other used MOLA with THEMIS daytime IR product draped over it. The shaded relief maps was originally delivered in Equidistant Cylindrical projection centered at 0 latitude and 0 longitude. The maps were re-projected into the same coordinate systems as the CRISM IR/VNIR browse images at PDS Geosciences Node. The re-projected shaded relief maps were moved slightly in the horizontal direction (x and y direction) in order to match with the features in the CRISM IR/VNIR images and THEMIS mosaics. The registration will not always be perfect between the layers at these resolutions. --------------- --------------- Using ArcGIS Maps 1) copy or download the "*.zip" files to your hard drive. 2) unzip the files. 3) Run "*.mxd" by double click, or open directly in Arcmap, currently supported by Arcmap 10 (*_AGS10.mxd) and Arcmap 9.3.1 (*_AGS931.mxd) ----Note---- In ArcMap, you can access the PDS products using the attribute information saved in footprint shape file through the following two methods. Method 1: use the Hyperlink tool in ArcMap to click the interested shape polygons in the map directly. A web browser will be opened automatically and linked to the ODE data product search page. Method 2: copy the url from the shape attribute table and open it in any web browser. 1) in the opened *.mxd file, in the left TOC window, select the shape file, right click, and select "Open Attribute Table", 2) in the pop-up attribute dialog, find the field named "ProductURL", you can copy the url link in the table by right click and selecting copy, 3) paste the url in a web browser, you can view the product directly in the ODE data product search page. -------------- -------------- Reference [1] Golombek M., J.
