Hi, I remember that I did tileindexes for vector layers a couple of years ago. I can’t find my example right now, but I think I was following this example for raster. The important thing is to have a one layer for the actual tile index, that has status off and one layer that is using the tile index layer. In my case I did it with sqlite if remember correctly. I believe I was following this example for raster, but did it with vector data.

I have the following tindex.geojson: { "type":"FeatureCollection","features":[{"type":"Feature","properties":{"location":"/app/mapfiles/test.geojson"},"geometry":{"type":"Polygon","coordinates":[[[122.013774753,29.96355712],[122.014247522,29.915620561],[122.06927508,29.916020438],[122.068828693,29.963957768],[122.013774753,29.96355712]]]}}]} Which points to a single file /app/mapfiles/test.geojson: {"type":"Feature","properties":{},"geometry":{"coordinates":[[[122.04067791363536,29.944772490597998],[122.03620089848994,29.94141730774004],[122.03819740524398,29.937852301951125],[122.0446709271447,29.938166866424368],[122.04648593328471,29.940211511256464],[122.04067791363536,29.944772490597998]]],"type":"Polygon"}} I would like to define the TILEINDEX as one MapServer Layer and have another MapServer layer reference that tile index. I tried this layer: LAYER NAME "vector_via_ogr" TYPE POLYGON TILEINDEX tindex_ogr CONNECTIONTYPE OGR STATUS OFF END but when I run `mapserv -nh QUERY_STRING='service=WFS&VERSION=1.0.0&REQUEST=getfeature&map=/app/mapfiles/test2.map&typename=vector_via_ogr&OUTPUTFORMAT=geojson'`, I get the following error: "msOGRFileOpen(): OGR error. Open failed for OGR connection in layer `vector_via_ogr'. File not found or unsupported format. Check server logs." If I run without CONNECTIONTYPE OGR, I get the following error: "msTiledSHPOpenFile(): Shapefile error. Tileindex layer must be a shapefile." I can get a similar thing working for a TILEINDEX of rasters. However I cannot get it working on a TILEINDEX of vectors. The example below is the simplest reproduce case I could create. Ultimately I plan on having a TILEINDEX point to a layer of defined via CONNECTIONTYPE postgis. How do I get a vector tileindex working with another Mapserver layer as the tileindex? Thanks! Pete Full mapfile below with example commands reproducing my errors.
