You can use Tilemill to create a cartocss style which you can then use with Mapnik (might need to convert to Mapnik XML). GeoServer supports SLD styles which you can create with many GIS tools, for example QGIS or OpenJUMP.

Yes, it's possible to fill a polygon with symbols on an angle. It cannot be done with Marker symbol type, only with Picture symbol type. Even with Picture it applies to the symbol as a whole, meaning you'd need to symbolize on your rotation field and set each one to the angle you want - the angle cannot be read automatically from a field (so far as I ...

Geopandas plot takes a colormap parameter GeoDataFrame.plot(column=None, colormap=None, alpha=0.5, categorical=False, legend=False, axes=None) The pandas documentation mentions colormaps such as colormap='cubehelix' colormap='Greens' colormap='winter'

Have you tried using the SVG icons that CartoDB offers in the image selector window? There are already some basic figures available there that don't look pixelated once used in the map :-)

If this is for simply viewing or creating a map without the built in ESRI legend i would just do this, in your table of contents you can left click on the color box (the actual color you want to exclude) and the color selector menu will appear, then click on properties and select the box that says "Color is Null" this will remove that color from your map ...

I was just playing around with this and it seems that when you use data exclusion, it excludes the data (in this case 0), but still lists it in the range and label columns. My suggestions would be to manually change the label column to read what you want it to read (click on the label text within the symbology tab). You can double check that the 0 data ...

An option that has worked for me is using the data source options you have from python. This has allowed me to write a script to transfer pie chart symbology, which isn't possible for some reason with standard tools. It also lets me repair broken links where symbology gets dropped when the data source is relinked from layer properties. You can also relink ...

Since arcpy doesn't let you customize your layers, and only load symbology from already-created layers, you'll need a library of layers for all your potential combinations of values. Then you're going to have to figure out a way to reference the correct layer file for your layer that suits your data. Something like this perhaps. I find the min and max ...

Since you know exactly what you want your new symbolization to be, I would suggest saving a layer file with that symbolization. In arcmap, add a test layer to your table of contents, and symbolize it as desired (1-100 orange, 101-200 red, 201-300 blue). Then right-click on the layer in the table of contents and 'Save As Layer File...' This lets you save the ...

This can be accomplished by adding a marker line symbol to your line symbol.In the symbol property editor add a layer to the line by pressing the 'plus' button in the layer window. Once you have added the layer select 'Marker Line Symbol' from the 'Type' drop-down menu. Now press the 'Symbol' button and select the 'Triangle 1' symbol and adjust the size ...

As the comment above said; you need to open the properties of your layer (either double click it or right click it and choose properties), go to Style tab, and change from Single Symbol to Graduated. Then you choose the attribute you want to use in the drop down, choose a colour gradient and press Classify. However, if your attribute is the wrong data type ...

This cannot be done with ArcGIS. I asked a similar question here: Symbolizing File Geodatabase feature class with Layer File created from AutoCAD drawing? Personally, I was at least hoping to create a layer file from the CAD drawing that was added to ArcMap (similar symbology to what it appears like in AutoCAD but not identical). Although saving CAD layer ...

You can specify a data-defined override using the button right next to the angle input In previous QGIS versions, this functionality was available through the data-defined properties button.

If you wish to see this functionality in ArcGIS for Desktop then I think you will need to submit it as a new ArcGIS Idea. My recommendation would be to post it under the product category of ArcGIS Pro rather than ArcGIS Desktop. In the meantime, about all I could uncover that seemed like it might be related was a comment from Charlie Frye on an old blog ...

1.) prepare symbols: - create a quadratic image, format png, e.g. 200x200px - content: a half circle, color xyz - rest of image: transparent - save file as file a.png - copy file to file b.png - edit file b.png and change color of half-circle 2.) edit symbology: - quantities, graduated symbol - click on Template, edit symbol, type: picture marker symbol - ...

You can select a Categorized (2.) symbology under Layer Properties -> Style (1.). To define custom colours for every single value, you can classify (4.) the layer with the selected attribute column (3.). After the automatic classification, you can assign a different colour for every different field value by double clicking the coloured square under Symbol ...
