| 测试用例2_postgis 数据库检索与创建 | |||
（1）看版本
SELECT postgis_full_version();
（2） 导入数据
> shp2pgsql -s 2270 -D jacksonco_schools.shp jacksonco_schools > jacksonco_schools.sql
> psql -f jacksonco_schools.sql workshop
（3） 创建数据表
CREATE TABLE points (name varchar, point geometry);
INSERT INTO points VALUES ('Origin', 'POINT(0 0)'),
('North', 'POINT(0 1)'),
('East', 'POINT(1 0)'),
('West', 'POINT(-1 0)'),
('South', 'POINT(0 -1)');
SELECT name, ST_AsText(point) FROM points;
（4）插入线段
INSERT INTO points VALUES
('Not a point', 'LINESTRING(1 1, -1 -1)'),
('3d point', 'POINT(0 0 3)'),
('WGS84 point', ST_SetSRID('POINT(0 1)', 4326));
（5） 检索
SELECT grade, category, type, name, students, ST_AsText(the_geom)
FROM jacksonco_schools
LIMIT 1;
（6） 3d 数据
Here are examples of a 3D linestring (in both WKT and WKB):
SELECT ST_AsEWKT(ST_GeometryFromText('LINESTRING(0 0 0,1 0 0,1 1 2)'));
（7） 测量数据
SELECT ST_Length(ST_GeomFromText('LINESTRING(0 0,5 0,5 10)'));
SELECT ST_Length(ST_GeomFromEWKT('LINESTRING(0 0 0,5 0 3,5 10 5)'));
SELECT ST_Length3D(ST_GeomFromEWKT('LINESTRING(0 0 0,5 0 3,5 10 5)'));
（8 ） 带坐标的测量
SELECT
ST_Length2D_Spheroid(g, 'SPHEROID["GRS 1980",6378137,298.257222101]'),
ST_Length3D_Spheroid(g, 'SPHEROID["GRS 1980",6378137,298.257222101]')
FROM (
VALUES (
ST_GeomFromEWKT('LINESTRING(151.1205 -33.7145 22,151.1218 -33.7087 54)')
) ) AS query(g);
（9） 测周长
SELECT ST_Perimeter(ST_GeomFromEWKT(g))
FROM (
VALUES
('POLYGON((-2 -2 0,2 -2 1,2 2 2,-2 2 1,-2 -2 0))'),
('POLYGON((-2 -2,2 -2,2 2,-2 2,-2 -2),(1 1,-1 1,-1 -1,1 -1,1 1))')
) AS query(g);
（10） 测外周长
SELECT
ST_Length(
ST_ExteriorRing(
ST_GeomFromEWKT(
'POLYGON((-2 -2,2 -2,2 2,-2 2,-2 -2),(1 1,-1 1,-1 -1,1 -1,1 1))'
)
)
);
（11） 测面积
SELECT ST_Area(ST_GeomFromEWKT(g))
FROM (
VALUES
('POLYGON((-2 -2 0,2 -2 1,2 2 2,-2 2 1,-2 -2 0))'),
('POLYGON((-2 -2,2 -2,2 2,-2 2,-2 -2),(1 1,-1 1,-1 -1,1 -1,1 1))')
) AS query(g);
（13） 测距离
SELECT ST_Distance(ST_GeomFromEWKT('POINT(0 5)'),
ST_GeomFromEWKT('LINESTRING(-2 2,2 2)'));
SELECT
ST_Distance_Sphere(a, b),
ST_Distance_Spheroid(a, b, 'SPHEROID["GRS 1980",6378137,298.257222101]')
FROM (
VALUES (
ST_GeomFromText('POINT(151.1205 -33.7145)'),
ST_GeomFromText('POINT(151.1218 -33.7087)')
) ) AS query (a, b);
（14） 测缓冲区 包含
SELECT namelow
FROM jacksonco_streets, medford_parks
WHERE ST_Distance(medford_parks.the_geom,
jacksonco_streets.the_geom) < 5000 / 0.3048
AND medford_parks.name = 'Hawthorne Park / Pool';
SELECT namelow
FROM jacksonco_streets, medford_parks
WHERE ST_DWithin(medford_parks.the_geom,
jacksonco_streets.the_geom, 5000 / 0.3048)
AND medford_parks.name = 'Hawthorne Park / Pool';

(1)1测试用例
public class qwe {
public static final void main(String[] args){
System.out.println("系统测试 1");
}
}
（2） openlayers 控件加载
基本思路：先创建地图map，然后添加图层layer，在添加控件control，以及增添属性feature，最后是增加事件event等其他业务逻辑。
map = new OpenLayers.Map('map'); //创建地图对象
//加载一个WMS图层
var layer = new OpenLayers.Layer.WMS( "基础图层",
"http://localhost:8080/geoserver/wms ", {layers: 'topp:basic'} ); map.addLayer(layer);
//加载一个Vector图层
vlayer = new OpenLayers.Layer.Vector( "自定义图层" );
map.addLayer(vlayer);
//设置中心
map.setCenter(new OpenLayers.LonLat(lon, lat), zoom);
//设置坐标显示的位置
var MPosition = new OpenLayers.Control.MousePosition({
div: document.getElementById("MousePosition-id")});
map.addControl(MPosition);
// 加载多个控件
map.addControl(new OpenLayers.Control.ScaleLine());
map.addControl(new OpenLayers.Control.MouseToolbar());
map.addControl(new OpenLayers.Control.LayerSwitcher({'ascending':false}));
map.addControl(new OpenLayers.Control.OverviewMap());
map.addControl(new OpenLayers.Control.EditingToolbar(vlayer));
map.addControl(new OpenLayers.Control.KeyboardDefaults());
map.addControl(new OpenLayers.Control.Permalink('permalink'));
