9/12 GIS課程一

這是我第一次上GIS課程
上完我才知道畫一張地圖需要注意許多事項
平常我們看地圖就只是要知道路線而已
從來沒想過原來要畫一張地圖這麼麻煩
畫一張簡單的地圖需要：
1.比例尺
2.指北針(方向、方位)
3.圖例(地標、註記)
4.圖名
5.製圖時間
6.測圖單位
以上是畫一張地圖最必須的項目




A thematic map is a map that emphasizes a particular theme or special topic such as the average distribution of rainfall in an area. They are different from general reference maps because they do not just show natural features like rivers, cities, political subdivisions and highways. Instead, if these items are on a thematic map, they are simply used as reference points to enhance one's understanding of the map's theme and purpose.

主題圖和一般參考地圖不同，不只是顯示河川、城市的分界更是強調一個特定的主題，例如平均降雨量分布、人文分布等
