[GIS] export the RGB values from an ArcGIS layer symbology

arcgis-desktopcolorqgisrgbsymbology

I've got a point layer in ArcGIS that has 100 specific color codes based on the name of the store. I'm trying to export the RGB values for these colors (along with the name value it's tied to) so I can create a qml style file for QGIS.

So, basically I'm trying to apply ArcGIS symobology rules into a QGIS qgs project.

Anyone know how I can do this?

I found this GEO thread Link which uses the java script API on server to extract from the JSON file. Might be worth further investigation.

Try to modify this template:

**Here is an example of a working .qml:**
`<!DOCTYPE qgis PUBLIC 'http://mrcc.com/qgis.dtd' 'SYSTEM'>
<qgis version="2.18.18" minimumScale="inf" maximumScale="1e+08" hasScaleBasedVisibilityFlag="0">
  <pipe>
    <rasterrenderer opacity="1" alphaBand="-1" classificationMax="11.485" classificationMinMaxOrigin="unknown" band="1" classificationMin="0.5" type="singlebandpseudocolor">
      <rasterTransparency/>
      <rastershader>
        <colorrampshader colorRampType="DISCRETE" clip="0">
          <item alpha="179" value="1" label="&lt;= 1" color="#0571b0"/>
          <item alpha="179" value="4" label="1 - 4" color="#92c5de"/>
          <item alpha="179" value="6" label="4 - 6" color="#f7f7f7"/>
          <item alpha="179" value="8" label="6 - 8" color="#f4a582"/>
          <item alpha="166" value="inf" label="> 8" color="#ca0020"/>
        </colorrampshader>
      </rastershader>
    </rasterrenderer>

    <huesaturation colorizeGreen="128" colorizeOn="0" colorizeRed="255" colorizeBlue="128" grayscaleMode="0" saturation="0" colorizeStrength="100"/>
    <rasterresampler maxOversampling="2"/>
  </pipe>

[GIS] How to export a RGB image from Google Earth Engine

Looks like you haven't defined a variable called image - which is what you pass along to the visualize() function. Try changing your visualize line to:

var imageRGB = dataset.median().visualize({bands: ['B4', 'B3', 'B2'], min: 0, max: 2500});
print("rgb",imageRGB);

You’ll also need to update the geometry in your export because ‘image’ doesn’t exist:

Export.image.toDrive({
  scale: 30,
  image: imageRGB,
  description: 'example_image_RGB',
  fileFormat: 'GeoTIFF',
  region: geometry});
