地理信息系統(tǒng)學習心得(共7頁)

1、精選優(yōu)質文檔-傾情為你奉上地理信息系統(tǒng)學習心得在開學之際，通過導師的指導，選擇了地理信息系統(tǒng)這門課。通過張秋文老師的精心講解，我獲益匪淺。第一：掌握地理信息系統(tǒng)的基礎。地理信息系統(tǒng)（GIS ，Geographic Information System ）是一門綜合性學科，結合地理學與地圖學以及遙感和計算機科學，已經廣泛的應用在不同的領域，是用于輸入、存儲、查詢、分析和顯示地理數(shù)據(jù)的計算機系統(tǒng)。GIS 是一種基于計算機的工具，它可以對空間信息進行分析和處理（簡而言之，是對地球上存在的現(xiàn)象和發(fā)生的事件進行成圖和分析）。 GIS 技術把地圖這種獨特的視覺化效果和地理分析功能與一般的數(shù)據(jù)庫操作（例如查

2、詢和統(tǒng)計分析等）集成在一起。GIS 與其他信息系統(tǒng)最大的區(qū)別是對空間信息的存儲管理分析，從而使其在廣泛的公眾和個人企事業(yè)單位中解釋事件、預測結果、規(guī)劃戰(zhàn)略等中具有實用價值。地理信息系統(tǒng)工作原理：地理信息系統(tǒng)是將計算機硬件、軟件、地理數(shù)據(jù)以及系統(tǒng)管理人員組織而成的對任一形式的地理信息進行高效獲取、存儲、更新、操作、分析及顯示的集成。地理信息系統(tǒng)的應用：（1）GIS 用于全球環(huán)境變化動態(tài)監(jiān)測；（2）GIS 用于自然資源調查與管理；（3）GIS 用于監(jiān)測、預測；（4）GIS 用于城市、區(qū)域規(guī)劃和地籍管理；（5）GIS 的軍事應用；（6）GIS 用于電網(wǎng)輔助決策中；（7）GIS 還在金融業(yè)、保險業(yè)、公

3、共事業(yè)、社會治安、運輸導航、考古、醫(yī)療救護等領域得到了廣泛的應用。第二：地理信息系統(tǒng)拓寬了我的眼界、拓展了我的思維。在學習這門課以前，我在看水利信息化相關文獻，對GIS沒有絲毫了解，只是大概的知道GPS、RS，學了GIS后，我便有了一個想法。即通過GPS、RS與GIS的結合，實現(xiàn)灌區(qū)信息化的建設。通過網(wǎng)上信息的查閱，我了解到相關信息：灌區(qū)信息中70%以上與空間地理位置有關。網(wǎng)格GIS不僅可以用于存儲和管理海量灌區(qū)信息還可以用于灌區(qū)的可視化查詢與網(wǎng)上發(fā)布。利用其空間分析能力可直接為灌區(qū)灌溉決策提供輔助支持。在實際應用中，可以通過RS獲取農業(yè)自然資源、作物長勢、氣象趨勢、災害等動態(tài)信息，將這些信息

4、直接以柵格格式存入空間數(shù)據(jù)庫，為地理信息系統(tǒng)提供大量的定位定量觀測數(shù)據(jù)。利用GPS作為重點工程數(shù)據(jù)更新的手段，將采集的數(shù)據(jù)放入實時數(shù)據(jù)庫。利用地理信息系統(tǒng)自己所帶的功能結合其他數(shù)據(jù)對這些數(shù)據(jù)進行管理。此外，通過GIS技術，可以在多種復雜因素共同作用條件下，隨意假設或更改部分邊界條件，對可能出現(xiàn)的結果進行數(shù)字模擬和仿真，通過生產實踐經驗積累與反饋，實現(xiàn)灌區(qū)規(guī)劃和管理的優(yōu)化。GIS系統(tǒng)的建立，可以很大程度上提高行業(yè)內工作人員的效率，減少人力、物力、財力的輸出；可以提高灌區(qū)管理水平，提高水資源利用效率，加快灌區(qū)現(xiàn)代化的發(fā)展進程。第三：時時保持學習的姿態(tài)。在課堂上，僅僅學習的是GIS的理論知識，但是在

5、實際中我們還得學習GIS的應用知識，湯國安和楊昕編著的地理信息系統(tǒng)空間分析實驗教程就很好用。GIS在國內飛速發(fā)展，應用越來越廣泛，但是信息技術也在飛速發(fā)展，為了與時俱進，我們必須時時保持學習的姿態(tài)和熱情。GIS是未來發(fā)展趨勢，把握好趨勢，才能在競爭中處于不敗之地。GIS learning experienceAt the beginning of the term, through the guidance of my instructor, I chose the GIS course.
