Introducing Map Sheets
Today we’re taking a major step forward with improved support for local data that doesn’t fit well into our nationwide layers. We are calling this feature “Map Sheets” and it replaces the former Geospatial Images option with a lot of improvements. Map sheets are any geospatial image that can be referenced and placed on a map such as a JPG, TIFF, or PDF file. To start exploring the layer head here. For more details read on below.
Any user can submit a map to be reviewed for this layer at caltopo.com/submitmap CalTopo will review the map for quality as well as assess any copyright issues. If you are a copyright holder of a number of maps (such as a representative of a trails organization, local government, or parks organization) please e-mail us at firstname.lastname@example.org to discuss copyright. CalTopo will provide on map hosting of your content and help provide it to other CalTopo users.
For pro, desktop, and team users we’ve also added the ability to upload a map sheet for personal use, including hosting of files by CalTopo! If the data source contains geospatial alignment data (such as a georeferenced PDF file) the file will automatically be placed in the correct spot, otherwise manual alignment is still required. This supplements and replaces the former “Geospatial Image” layer. This has been moved to a paid feature since CalTopo is now hosting an image. If you previously had Geospatial images in your account you’ll still access to those images
