Tahapan Membangun Aplikasi GIS… What Can ArcView Do? Display information which resides locally or over a distributed network. Read spatial and tabular information from a variety of data formats. Use colors and symbols to represent features. For example, rivers can be represented as blue solid lines, and roads as black dashed lines. Use colors and symbols to represent features based on their attributes. For example, counties (kabupaten) can be shaded based on their population. What Can ArcView Do?... Connect spatial information to database attributes: Select data spatially and retrieve database information. Select data from the database and see the spatial representation of the selected features. Provide analytical tools to answer spatial questions need. Data Types used in ArcView A. Geographic Data Geographic data consists of features represented by points, lines and polygons. ArcView can use: ArcView shape files (*.SHP) ARC/INFO coverages (PC or Unix) AutoCAD (*.DWG) and Microstation (*.DGN) CAD drawings DXF files Data Types used in ArcView B. Attribute Data ArcView can read tabular data from: dBASE files Database servers such as ORACLE, INGRES, SYBASE, INFORMIX etc. INFO tables Comma or tab delimited ascii files Data Types used in ArcView C. Image Data Image data includes satellite images, aerial photographs, and other remotely sensed or scanned data. Supported formats include: ARC/INFO GRID BSQ, BIL, BMP, BIP, and JPEG SUN raster files Tiff, TIFF LZW compressed, and GeoTIFF Erdas (.lan) Erdas Imagine Images (*.img) Image catalogs Run length compressed formats Data Types used in ArcView D. Grid Data Supported formats include: ARC/INFO GRID ASCII raster file format Binary raster file format USGS DEM format US DMA Digital Terrain Elevation Data (DTED) ArcView GUI: ArcView Components Projects Tables All components associated Rows (usually geographic locations, with a particular undertaking linked by ID to theme features) Comprised of views, tables, Columns describe attributes charts, layouts, scripts (characteristics) of locations View Chart Essentially a map which you Business graphics to display look at or view geographic and tabular data Contains one or more themes Layout Themes Graphic output/screen display of Layers of spatial data with views, tables, charts similar characteristics (eg Script streets, hydrology, capitals) Automation feature written in In ARC/INFO called coverage Avenue which allows full if vector, grid if raster customization ArcView GUI: Project (workspace) All components (‘documents’) associated with a particular Project undertaking stored in file with output extension *.apr Layout database Components dynamically updated: change one part, other parts updated accordingly. Chart Table business graphics View scripts geographic features (provide automation, (a map with one or more themes) special effects, etc) ArcView GUI: Views & Themes A view is essentially a map which you look GIS Framework at (view) on the screen (or print with layout). roads It contains one or more themes (ARCINFO coverages/grids) which are layers of spatial data with similar characteristics eg streets, hydrology hydrolgy, capitals. Only one view active at a time topography Themes listed in ArcView Table of Contents which allows you to control themes to be viewed. Data is organized by layers, Themes are added from View window coverages or themes using View pull down menu. (synonomous concepts), each representing a common feature. ArcView GUI: Tables & Charts Contains attribute (descriptive) data. Area Bar Can create in ArcView or access data from other sources (e.g via SQL). References to tables are stored, not data itself (therefore automatic update) Line Column Event tables contain geographic references and can be mapped (non-event tables can simply be included in layouts) Charts can be used to display tabular data. Pie Scatter 6 types: area, bar, column, line, pie, scatter Since data is stored in dBase tables and Excel can read these, it’s often as easy to use Excel (or similar) for graphing, especially for “one-off” charts.

Take steps within ArcView as appropriate for specific script e.g. Open a View and be sure the theme you want processed is active. Click on script window then click the “Runner" icon to run script. Getting Help The help button brings up a help menu. When using the main help index, click on the areas for which you need help. When using search, type in a topic name, scroll through the lists, then double click on the desired area. To find a listing of frequently asked questions (FAQ), search for ’questions’. The index is also helpful to look for keywords. Other Source of Help Personal Contact Ask your neighbors The best method of getting help is to ask other users around you. Inversely, the best way to improve your knowledge of how to do something is to explain it to someone else.
