<DIV> </DIV>
<DIV>Here are some features I think would be nice to have in Mapserver: </DIV>
<DIV><BR>** Expressions almost everywhere ** <BR>Possibility to use expressions whenever a value is required. <BR>Built-in variables and functions would be very useful. <BR>For example: <BR> SIZE [fieldValue]*0.2+5 <BR> WIDTH imageWidth / 200.0 # imageWidth is a built-in variable containing the map width in pixels <BR> SIZE min(5, [fieldValue]/100) # minimum function <BR> TEXT upperCase([fieldValue]) # get upper case value of a text field <BR> TEXT if([fieldValue] = "-", "Yes", "No") # "if then else" expression <BR> COLOR rampColor([fieldValue],0,10000) # get a color in a ramp for a numeric field normalized to a range </DIV>
<DIV> </DIV>
<DIV>** Finer grained concurrency locks ** <BR>Especially in OGR. Currently Mapscript (Java or .NET) is not an efficient option on a webserver accessing OGR: web requests are practically serialized by the locks. <BR>I think thread safety was improved in latest version of GDAL/OGR, am I wrong? <BR>Adopting RFC15 would be great news! </DIV>
<DIV> </DIV>
<DIV>** Facilities for tiles ** <BR>Given the big performance boost of using map tiles, I think it would be very useful an utility (or API) for pregenerating tiles of a map for a given area and level. <BR>I am aware of the existence of TileCache but I think it would be interesting to have this utility. </DIV>
<DIV> </DIV>
<DIV>** Multiple geometry types on a layer ** <BR>Currently, a layer only admits one geometry type (point, line, polygon). Some sources, especially CAD datasets via OGR, <BR>contain different geometry types. Would be useful and efficient to have all geometries shown in the same layer. <BR>Different styling rules may be needed to display different geometry types in the same layer. </DIV>
