Geologic Map of Morava Valles, Mars
GIS version
---------------

Rationale and Intent:
This geologic map was authored by Sharon A. Wilson in 2020, and has been digitized as a GIS product for public release.  Please use the original citation:

Wilson, S.A., Grant, J.A., and Williams, K.K., 2022, Geologic map of MTM -10022 and -15022 quadrangles, Morava Valles and Margaritifer basin, Mars: U.S. Geological Survey Scientific Investigations Map 3489, pamphlet 11 p., 1 sheet, scale 1:500,000, https://doi.org/10.3133/SIM3489.

---------------

Project specific datasets are projected (meters).
Projection: Mars Transverse Mercator
            Central meridian: 340.0E
using the geographic coordinate system "Mars 2000"
Major and minor axes are 3396190.0 m
Also included is the *.prj file for the Mars 2000 Sphere GCS.  They are all located in ...\CoordinateSystems.

----------------

File geodatabase contains one feature dataset:
1.) MTM_clon340E
    a) Figures_FINAL (polygon file)
    b) GeoContacts_FINAL (polyline file)
    c) GeoUnits_FINAL (polygon file)
    d) GeoUnits_FINAL_Anno (annotation file)
    e) LinearFeatures_FINAL (polyline file)
    f) LocationFeatures_FINAL (point file)
    g) Map_Boundary (polygon file)
    h) Nomenclature_Anno (annotation file)
    i) SurfaceFeatures_FINAL (polygon file)

These feature classes are grouped into “Mapping Layers” in the ArcMap project.  They are projected as MTM and should house all digitized map information.

----------------

Raster layers are included in the folder ...\BaseMaps\, and include:
1.) Mars_MO_THEMIS_IR_Day_mosaic_100m_v12_clip.tif
2.) Mars_MO_THEMIS_IR_Night_mosaic_100m_v12_clip.tif
3.) Mars_Viking_MDIM21_mosaic_232m_clip.tif
4.) MOLA128_88Nto88S_Simp_clon0_lossless2_MargMap.tif

These feature classes are grouped into “Rasters” in the ArcMap project.  They are projected as MTM.

Supplemental raster layer available in the sim3489_SupplementalData.zip
1.) CTX_Mosaic_Beta01_Feb2018_MoravaValles_TMerc.tif

----------------
Symbols are applied to each of the included feature classes. These symbols are adapted from USGS Open File Report 99-430 (Digital Cartographic Standard for Geologic Map Symbolization). These can be viewed and downloaded at http://pubs.usgs.gov/of/1999/of99-430/

---------------

To add/remove symbols, open ArcMap project, right-click the feature class of interest, click “Properties”, and click “Symbology” tab. Highlight the symbol to alter and then click “Remove” or double-click to alter.  Each feature class has an associated *.lyr file that houses the symbologies.  Click “import” on the “Symbology” tab and navigate to the appropriate *.lyr to return to the full symbol list.

----------------

We suggest that all work is contained within the *\Working folder. Create sub-folders as necessary to house relevant GIS data and map data.

Comments are encouraged in order to assimilate beneficial GIS-based tools, datasets, and mapping approaches for future mappers.
