B y integra2 ting new powerful technologies into GIS system s, we get higher perform ance results w ith additional functionalities. The most recent development cap turing the attention of the brow ser2based2app lication developers is the component development technology based Google M ap s and Joom la. In this paper, the authors describe the recent situation of Google Map s and analyse its realization app lication in Joom la site, then p rovide a set of Google Map s design frame and four modules in Joom la. The component is imp lemented by using PHP and Java scrip t language based on Joom la framework and Google Map sap I. W ith the component, we can embed Google Map s in own web pages sim2 p ly, draw markers and lines on the map fleetly, and build sophisticated app lications w ith our own objective easily.
