Welcome to Avalon Maps
Description
The maps on this site are raster maps - dots rather than vector data - which means you can work on them in exactly the same way as you work on your scanned images or digital photos.
The Basemaps and Historical Survey Maps are large, from 12 to 62 megapixels in size. To permit a practical download file size, they are supplied as 8-bit/256 colour .png files. This means that you will be able to cut, crop, and paint the maps with you own data, but if you want to carry out global colour operations such as adjusting brightness or applying special effects you will need to increase the colour depth (usually to 24-bit/16 million colours). Most picture-editing software can do this, but if colour operations are important to you we suggest you confirm the capability of your software first.
If there is no explicit colour depth command, try a "save as" option. Saving as .jpg or as .png "true colour" will automatically increase the colour depth. If saving as .jpg, use the highest possible quality setting, and don't discard the download file.
