Visually create spatial database

Easily populating with data

Shapefile Loader Plugin

Query editor CREATE TABLE "smallworld" (gid serial PRIMARY

KEY, "placename" varchar(50), "comment" varchar(255)

, "year" numeric);

SELECT AddGeometryColumn('','smallworld','the_geom',

'4326','POINT',2);

INSERT INTO smallworld (the_geom, placename, comment,

year) VALUES (ST_GeomFromText('POINT(51.05

Hierarchical structure

Workspace used to group similar

data

Store, a container for geographical

data (any data source supported)

Layer, collection of features or a

coverage

Layer group, grouping of layers

Style as a visualization directive

for rendering geographic data

OpenLayers Javascript web mapping framework:

<script src="openlayers/OpenLayers.js"></script> ...

<div id="map-id”></div> <script> var map = new OpenLayers.Map("map-id");

var world = new OpenLayers.Layer.WMS(

"Earth",

"http://localhost:8080/geoserver/wms", {layers: "earthgroup”}

);

map.addLayer(world);

map.zoomToMaxExtent();

</script>

You can add layers and controls
