首先,我是地理信息系统和开放式媒体领域的一个新手,因此请与我在一起。 我正在使用一个开放式地图,在地图上显示各省的边界,同时为每个省增加一个背景(见以下图象,例如:http://afghanistanelectiondata.org/open/maps/Functions/afghanistan-hillshade-english)。
1-我想知道背景和边界是如何划定的? 不管我们心中和外的多少,它们如何存在?
2- 从带边界的图像带入哪里,我们是否引出这些图像,或者我们是否应当绘制边界地图,将其放在地图上?
3- Anyone who has an example which wrap all the concepts all together (preferably with Drupal)?
The background and borders are pre-rendered tileset, generated and served with MapBox. You ll need to do some reading up on creating tiles and using them in OpenLayers.
你们把地图带上边界,把它放在地图上。 但首先,你们需要创造具有各省边界的透明tile。
