I have a massive shapefile with 200,000+ building polygons. I've loaded these up in ArcGIS. I need to convert this into a usable raster (GeoTIFF) that can then be tiled using MapTiler.
My current process is as follows:
- Click on the Full Extent icon in order to have all the polygons in my current view. The scale is at 1:261,289.
- Export this as raster using File > Export Map > TIFF > Write GeoTIFF tags (in Format tab). Set the dpi to 500.
- When zoomed all the way into this GeoTIFF image, the result looks too pixelated. You can barely tell they are polygons.
I need to the scale to be at 1:26,261 (or 1:25,000 for simplicity) in order to get decent looking polygons.
How can I create a grid over this vector file with 200,000+ polygons and then save each section into a GeoTIFF file at 1:26,261 scale?
I also tried this in QGIS. Similar issues, though somewhat better results in ArcGIS.
