我不知道从哪里开始 GIS 应用程序开发，或者选择哪种技术
我对 GIS 开发非常陌生，坦白说我完全没有这方面的背景。我在网上搜索，但我发现的教程似乎假设读者有一些背景信息。
问题是我对读什么或学什么感到困惑，似乎有很多技术，而且我感到迷失，因为有些人谈论 openlayers、geoserver、mapserver、google 地图和开放街道地图。
所以这就是我应该开发的内容，我希望你能给我一个关于使用哪种技术的建议，以及我应该从哪里开始阅读 - 鉴于我几乎一无所知 - 。
案例 1：仅容纳约 20 个用户的封闭系统，他们可以在地图上指定位置，Web 应用程序将存储位置的纬度和经度并显示标记。我想使用谷歌地图API，但我取消了这一点，因为如果系统是封闭的，那么许可证要求您购买该服务。那么在这种情况下我应该使用什么技术呢？我需要一个免费选项，而且我将只使用网络服务器，所以如果解决方案包括使用我自己的地理服务器或类似的东西，我将无法做到这一点。
情况 2：我应该显示两个给定点之间的道路和路线，并可能在地图上添加一些注释。对于这种情况，我可以使用自己的地图服务器/地理服务器，但我再次需要您的建议。
当然解决方案最终需要开源
，我希望你能告诉我先开始阅读什么，
I am very new to GIS development, and to be be frank I have no background about it at all. I searched the web but the tutorials I found seemed to assume the reader has some background information.
the thing is that I am confused about what to read or learn, there seems to be lots of technologies, and I feel lost since some speak about openlayers, geoserver, mapserver, google maps, and open street maps.
So here is what I am supposed to develop, and I hove you could give me an advice about which technology to use, and where should I start reading - given that I know almost nothing -.
Case 1: a closed system for about 20 users only, who can specify locations on the map, and the web application will store the latitude and longitude of the locations and show the markers. I wanted to use google maps api, but I cancelled that since there license requires you to purchase the service if the system is a closed one. so what technology should I use in such case? I need a free option, also I will be only using web server, so if the solution includes using my own geoserver, or something like that I won't be able to do it.
Case 2: I am supposed to display the roads and routes between two given points, and probably add some notes on the map. For this I case I can use my own map server/geo server, but again I want your suggestions.
of course the solution need to be open source
finally, I hope you could tell me what to start reading first,
