對構建具有GIS(地理信息系統)數據查看特征(矢量覆蓋和圖象)和矢量畫圖編輯的WEB應用程序的開發者來說,DbMAP ASJ是一款技術非常先進的工具。
DbMAP ASJ is an advanced tool for web application developers oriented to build HTML pages, JSP pages and other types of dynamic Web pages (ASP, PHP, etc.) with GIS data view features (vector coverages and imagery) and vectorial drawing editing.

顯示的內容可以通過一個XML工程(靜態文件或者服務器端動態生成的文件)來完全量身定制。
Java Applets:
-
顯示光柵圖象
-
基于對ORACLE空間表/定位表進行Select操作來構建對象。
-
編輯或者創建對象,并且可以將其保存到ORACLE空間表/定位表中。
-
可以縱覽地圖,移動并且縮放地圖,關閉或者打開圖層,改變顯示參數,顯示名稱等。
Java Servlets:
-
當進行Select查詢ORACLE空間表/定位表時,會給Applets傳遞許多顯示的向量。(只有建立了與ORACLE服務器端連接才可以)
-
可以傳遞壓縮的鑲嵌圖象給Applets.
-
可以根據客戶要求來提供給客戶AutoCAD(DWG)圖像的組成部分和GeoTiff(地理標簽圖象文件)
Java 程序開發員還可以:
-
開發新的Applets,并且將DbMAP ASJ完全整合在其中。
-
修改由DbMAP ASJ提供的附屬Applets——并附帶有DbMAP ASJ相關源代碼。
主要功能:
-
geospatial數據庫:ORACLE? 空間和定位器; Abaco? multi-standard SDA驅動器, 作為geospatial數據庫允許任何相關的數據庫使用。
-
向量文件: 支持AutoCAD? DWG和ESRI? shapefile(SHP)文件格式。
-
Raster imaginery:支持Oracle? Spatial georaster, ErMapper? (ECW/ECWP), MrSID? (SID) 和GeoTIFF/TFW文件格式。
-
支持主題,層,面板,縮放,概述,剖面線,編輯,快照,搜索,打印等功能。
技術說明
-
服務器: 與J2EE(支持Java Servlet), Oracle 9i和Spatial 10g, 定位器或其他的RDBMS服務器兼容。
-
客戶端: Java兼容的瀏覽器,像Internet Explorer,Netscape Navigator等瀏覽器一樣。
-
兼容性: 可在MS-Windows (所有的版本), Linux, Mac OS X, Pocket PC等版本中進行測試。

The displayed content can be fully customized using an XML project (static file or dynamically produced on the server).
JAVA Applets:
-
Display raster images;
-
Draw objects based on selections from ORACLE? Spatial/Locator table;
-
Edit or create objects, and save them in ORACLE? Spatial/Locator tables;
-
Perform overview, pan and zoom, layers on/off, change display parameters, themes, etc.
JAVA Servlets:
-
Send the Applets a list of the vectors displayed when a selection from an Oracle Spatial/Locator table is performed (ORACLE connection from server side only);
-
Send compressed, mosaiced rasters imagery to Applets;
-
Provide clients with portions of AutoCAD (DWG) drawings and GeoTIFF file as requested.
JAVA developers can also:
-
Develop new Applets fully integrated in DbMAP ASJ;
-
Modify satellite Applets supplied with DbMAP ASJ - source code is included.
MAIN FUNCTIONALITIES
-
geospatial database: ORACLE? Spatial and Locator; Abaco? multi-standard SDA driver, allowing the use of any relational database as a geospatial database.
-

-
raster imaginery: ORACLE? Spatial georaster, ErMapper? (ECW/ECWP), MrSID? (SID) and GeoTIFF/TFW format.
-
supports: Themes, layers, pan, zoom, overview, hatches, editing, snap, searches, prints, etc.
TECHNICAL SPECIFICATIONS
-
server: Server J2EE compatible (supporting JAVA Servlet), ORACLE 9i and 10g Spatial, Locator or other RDBMS.
-
client: JAVA compatible browser, like Internet Explorer, Netscape Navigator, etc.
-
compatibility: Tested on MS-Windows (all versions), Linux, Mac OS X, Pocket PC, etc.
