This question is a well known cartographic problem, and there are several ways to implement: 1) Offset. Like the underground/tube maps of cities, lines running o same set of tracks appear next to one another, like these example in NYC. This is only applicable if you have a limited number of overlapping lines. 2) Color-based. Changing the color of the ...

If you don't have too many lines, you could make the lines underneath other lines thicker than ones above them. Symbolize the colors appropriately so they're visible, e.g. darker underneath, lighter on top. Another method would be to set upper lines to be dashed in some way, again with appropriate colors for visibility. I've seen, but not a fan of, lines ...

If the class breaks were derived from the rasters rgb values, you might use arcpy.GetCellValue_management tool with the features centroid against the original raster? Saving polygon symbology as RGB values in the attribute table

Without the Maplex label engine your only option using the Standard Label engine is to label each part of the feature: Maplex gives more functionality for labeling, to repeat the label go to label density and select the checkbox for Repeat Label: Hit the options button and specify how often you want the label to be repeated, either in map units or page ...

As pointed out by @radouxju the search for symbols functionality was introduced at ArcGIS 10.0 and from a blog enitled Symbols and styles in ArcGIS 10.0: Finding appropriate symbols to apply to your features and graphics is easy in ArcGIS 10 because you can search for and use symbols without having to know to which style they belong, nor have that ...

Essentially the same way the labels are. Go to the General tab instead of the Label tab of the layer properties. There you'll find the same Scale Range settings as for labels. However, unlike labels, the layer itself doesn't offer classes so you can't have one group show up at scale A and another at scale B. The way around this is to add the data as multiple ...

QGIS can read QML and SLD style files. If you only have access to proprietary style formats, QGIS won't be able to read those because the specifications are not public.

I recommend that you vote for an ArcGIS Idea entitled Draw vertices: It would be nice to display vertices at all time. Currently a line has to be selected for it to draw vertices. Maybe a button to turn it on and off.

Turns out that CreateMarkerSymbolFromFile actually works with PNG, despite of the docs saying it only works with BMP and EMF. Didn't work when I tried it at first, but probably due to some other error. Anyway, just use CreateMarkerSymbolFromFile with esriIPictureType.esriIPicturePNG and it works fine.

This is possible in the ArcGIS Server JavaScript API using the Dot Density Renderer: The DotDensityRenderer provides the ability to create dot density visualizations on data. A dot density map can be used to visualize the variation in spatial density of a discrete spatial phenomenon. There is a sample available here. (I'm not sure whether it's ...

The short answer is you can't. The graduated symbols are treated more like labels (which essentially they are - special labels at the centroid of the polygon), which draw on top of all actual features. Layer order will control the draw order of various graduated symbol layers. It also controls the draw order of the background of a graduated symbol layer; ...

An alternative approach is to use Representations or Linear Referencing to create offset cartographic lines without adjusting their underlying geometry. For the LR approach cartographic side distances are applied to line events that include a field with positive or negative distance number that makes the line event offset left or right. Your bus routes ...

I solved a similar problem by using buffers to extend each line by what I estimated the accuracy of my lines to be (to smooth small imperfections). Then follow these steps Merge all buffers into one file Use union on the merged buffers Each overlapping area will be represented by identical polygons that are identical to each other, but are in the exact ...

For a purely graphical purpose, I would do an overlay (like Union) of all your route lines and in the resulting attribute table you'll either have or can add a field with a count of the number of lines that went into it. For example you may have one segment where A and C overlap but not B, or B and C but not A. The Union's results should have an attribute ...

Part of what you're running into is a screen resolution issue. Points can only be displayed down to a certain size relative to everything else, and sometimes values will fall between two distinguishable sizes and get rounded one way or the other on the screen. There are only so many individual pixels on your screen with which to draw everything. This effect ...

The short answer is yes, you can make points smaller than 1.0. There could be a few different things going on: (1) Are you in map view or layout view? The map data view may be scaling your points so that they appear the same size as you zoom in. (2) It is very difficult to eyeball the difference between 1.0 and 0.5, for example. On my screen they look the ...

The size they are represented is also linked to how big your map is when you are exporting it (assuming you are exporting it) so yes a point can be displayed at less than size 1 but it depnds on what you want to do next. However if you have a lot of points and reducing the size doesn't help an alternative that might be worth looking into is the Point ...

To label your features enable "Label this layer with" in the Layer properties > Labels by selecting the specific column from your attribute table. Then there are several possibilities to format the labels.

You can also use the "rule based" under the Style option if you have a different colum for each attribute (if schools are in a different colum from toilets).


2

In a first run, style your data using the categorized style on the attribute field. Then you can change every category style to fit your individual needs. Not only the colour as the default style does, but also another symbol, or SVG.

I certainly wish that more people would be as concerned about the display of digital elevation data as you are. I see so many examples of poorly rendered DEMs that it's somewhat disconcerting. So thank you for raising this question. First, to answer your question of "how can I be sure that I am using a correct setting", I don't think that there is such thing ...

Perhaps you could use the "Unique Values, Many Fields" symbology option and choose the number field then the description field: Then when you insert the legend it will show the number and the description: Its not perfect because it doesn't show the number inside the symbol but it might do the trick and I bet if you convert the legent to graphic then do ...

You can't easily display label information in the legend, so the best solution is to have unique symbology for each of your points. The simplest way to do this is to open the properties for your layer and and select the Categories option on the left hand side (see below). You can then select the field to create a different symbology for each point. ...

For a DEM, I would expect regular interval (similar to what you get with contour lines). Therefore, I would recommend a linear stretch. Maybe you could just increase the contrast in the area where you have the most data by sacrifying the contrast for the very few very high pixels (summits). So putting your line from the bottom left (0,0) to (6,8) counting ...

If your values are Normally distributed then approximately 68%, 95% & 99.7% of the values lie within 1, 2 & 3 Standard Deviations respectively, see here, so if you are stretching your values of the colour map using SD(2) all of the values that are below 2.5% will be black and all over 97.5% will be white, (depending on your colour scale of course) - ...

Remove the outline of the feature style in Layer Properties | Style or turn it white - depending on which effect you prefer.
