[mapserver-users] Arc symbol.

[Basques, Bob (CI-StPaul)]

Marek,

Landing your data into Postgres/PostGIS enables a bunch of capabilities.  Combined with MapServer as an output/convertor, you can essentially filter to your hearts content as well as reproject to just about any EPSG code with Ease.  We’ve even added to the EPSG lists in PostGIS for our own, custom local coordinate system.

The benefits of using Postgis as a data staging (caching) area far outweigh the extra effort of adding the data in.

Hello Bob,

It is not about data (the customer delivered data). It is about visualization. I have object to visualize - point (lat, lon) with degree range (min degree, max degree). The end user should see that object as an arc. There is support for ellipse/circle in mapserver SYMBOL but I did not found simply way to draw just part of cirle.

Regards,
Marek

This is related more to what type of data you want/need to save the data in.  Not all data formats understand Arc definitions.  Postgres for example does, as does AutoCAD (DXF).  The ESRI Rest services can (but I think it needs to be turned on from the server side.

Hello All,

Is it possible to create an arc symbol im mapserver? For example I have two lines constructed over some angle (ex. 30 degree) and I want to draw an arc between them.

Regards,

Marek
