I'm trying to learn and understand more about mapping and displaying values on a map. 我正在尝试学习和了解有关在地图上映射和显示值的更多信息。 (GIS) （地理信息系统）

At the moment I'M looking to take some values and apply those values to a tile or bin on a map. 目前，我正在寻找一些值，并将这些值应用于地图上的图块或垃圾箱。 Ideally I'd like the tile sizes to be uniform, like 100 meters, 500 meters, etc. 理想情况下，我希望瓷砖尺寸均匀，例如100米，500米等。

Is there a standard method for creating uniform tile sizes? 是否有创建统一图块大小的标准方法？ Or Are what are common accepted method to deal with this kind of data display? 或处理这种数据显示的通用方法是什么？

(Currently I'm using geodjango and it's related toolset geos, proj4, etc) （目前，我正在使用geodjango及其相关的工具集geos，proj4等）

It sounds like you want to be working with geospatial raster image formats, where the color of a pixel represents the value for that tile. 听起来好像您想使用地理空间栅格图像格式，其中像素的颜色代表该图块的值。

The size of a tile (and whether it's uniform) will depend on the projection of your raster. 瓦片的大小（以及是否均匀）将取决于栅格的投影。

GDAL is a library for working with geospatial raster formats. GDAL是用于处理地理空间栅格格式的库。
