Marin aerial

I have the orthophotos in TIFF format downloaded and I want to use them in a web map.

I need to convert them into raster tiles. I already wrote about this in Mapping Vietnam, here is how I did it for the Marin data.

I have every TIFF image in a folder. I can make a mosaic in one step with

gdalbuild marin.vrt *.tif

This creates a file that lists the members of the mosaic, it takes a couple seconds. Now I can process all the TIFF files at once with the remaining commands.

Reproject

Build tiles
