1 Page 1 of 13 RESIN GIS Workshop #1, November 6, 2009, John Radke, Howard Foster 0 Basic concepts of GIS data and functionality 1 Design of the RESIN GIS data library 2 Server (connecting to the server), files as backup 3 GIS clients, advantages and disadvantages of various clients 4 Client: Arc Explorer.net and java (adding layers, annotations, symbology) 5 Client: GISC s MapView (adding layers, symbology, editing points, lines, polygon files, saving layers) 6 Brief discussion of the advanced ArcMap 7 Field expectations (identified groups, group themes, locations ground truth) 8 Trouble shooting, redundancy For the best results...just follow the yellow brick road 4 ArcGIS Explorer java Download the software here: Java Edition for Education Download documentation here: Introduction to ArcExplorer Java Edition for Education [PDF] Start the ArcExplorer software A window appears with a legend area on the left and a mapping area on the right.

2 Page 2 of 13 From the Main Menu select File and Open... Go to the directory with the saved Map file of shapefiles... If you followed our protocol in the workshop this file is located at... C:\TEMP\RESIN\green And all the shapefiles that were clipped data of Sherman Island should be located at...c:\temp\resin\si_clipped_sp83

3 Page 3 of 13 This map should appear and the data is projected in California State Plane, Zone 3, NAD83. The Data Frame or Table of Content, The Viewing Tools, The Map Area...defined Turn data layers off and on in the Data Frame..Note that data layers on top in the Data Frame over write those underneath. You can click and drag layers ontop of each other to change the order of display.

4 Page 4 of 13 Navigating around the Map Area: Zoom in and out... Pan..

5 Page 5 of 13 Zoom to Full Extent Identify a polygon, line or point feature..the data appears for a given object selcted. highlight the layer to identify...deltasuisun_marsh_vegetation in this instance.

6 Page 6 of 13 Identify the polygon in this instance... and get the data record associated with the object (polygon in this instance). Lets look at the entire data table for a given layer... right click on the data layer that you wish to open. Select the Attribute Table. The table appears with all data Records and data Fields

7 Page 7 of 13 Loading more data layers to the Data Frame..Launch the Content Chooser Select a data layer... It loads the layer to the Data Frame and displays it in the Map Area with a default Symbology (which appears random here).

8 Page 8 of 13 Lets change its Symbology. Right click on the layer that you wish to change its Symbology and select Properties. An editing wizard opens.. Select the pull down window and select a default color or choose custom.

9 Page 9 of 13 I choose custom and launch an array of colors.. I choose a red and it reveals its color content here (255,0,0). The 500kv electric distribution lines are now a thick red symbol.

10 Page 10 of 13 We can also modify more complex symbology..load the deltasuisun_marsh_vegetation a second time. Note: It loads a a solid color. Turn off all layers but this latest one that you have added..

11 Page 11 of 13 Right click on this layer and launch Properties.. Rather than One Symbol choose Unique Symbols.. Then choose urs_type...

12 Page 12 of 13 You can automatically choose from a few dirrect pallets... Or you can choose the colors of each value separately and change its color. Here I change water to a Blue color.

13 Page 13 of 13 Finish with a demonstration of continuous data display
