Geologic Map of the Nepenthes Planum Region, Mars
GIS version
---------------

Rationale and Intent:
This geologic map was authored by James A. Skinner, Jr. and Kenneth L. Tanaka in 2018, and has been digitized as a GIS product for public release.  Please use the original citation:

Skinner, J.A., and Tanaka, K.L. 2018, Geologic Map of the Nepenthes Planum Region, Mars: U.S. Geological Survey Scientific Investigations Map 3389, pamphlet 11 p., 1 sheet, scale 1:1,506,000, https://doi.org/10.3133/sim3389.

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

Project specific datasets are projected (meters).
Projection: Mars Transverse Mercator
            Central meridian: 110.0
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.) UtopiaHLB_MTM
    a) Anno_11_33 (relationship class file)
    b) FigureLocations_AUG2017_ACCEPTED (polygon file)
    c) FigureNumbers_AUG2017_ACCEPTED (annotation file)
    d) GeoContacts_AUG2017_ACCEPTED (polyline file)
    e) GeoUnits_AUG2017_ACCEPTED (polygon file)
    f) GeoUnits_AUG2017_ACCEPTEDAnno (annotation file)
    g) LabelLeaders_SEPT2017_ACCEPTED (polyline file)
    h) LinearFeatures_AUG2017_ACCEPTED (polyline file)
    i) LocationFeatures_AUG2017_ACCEPTED (point file)
    j) MapBoundary_AUG2017_ACCEPTED (polygon file)
    k) Nomenclature_AUG2017_ACCEPTED (annotation file)
    l) SurfaceFeatures_AUG2017_ACCEPTED (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.) MOLA128_hlshd_MTM_clon110.tif
2.) MOLA128_MTM_clon110.tif
3.) THEMIS_IR_daytime_MTM_clon110.tif
4.) utopia_hlb_temp.tif

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

----------------
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.
