Spatial Data

A spatial view is a “window” into the

GIS database which gives users a

custom look at the geometries and

related information they need to use.

Spatial Views

GIS Client

Aggregated Data

Examples of Spatial Attributes &

Aggregation in Spatial Views:

SDO_GEOM.SDO_LENGTH

SDO_GEOM.SDO_AREA

SDO_GEOM.SDO_INTERSECTION

Spatial Views – Oracle Spatial and Graph Data Delivery

This SQL example creates an Oracle Spatial view

using SDO_INTERSECTION to assign field geometry

features to a geographic index. When combined with

other geographic indices, these attributes can be joined

back to the spatial features and commodity information

in a spatial view and be used as “GROUP BY” columns

for summarizing quantity statistics:

CREATE OR REPLACE VIEW VGIS_AN_FIELD_COLLECT_PT_GEO1

AS SELECT

input.OBJECTID OBJECTID,

input.FEAT_NAME FEAT_NAME,

input.FEAT_DESC FEAT_DESC,

target.GEOG1_INDEX TILE_CODE,

target.FEAT_NAME TILE_NAME,

SDO_GEOM.SDO_CENTROID(input.shape,0.001).SDO_POINT.X COORD_X,

SDO_GEOM.SDO_CENTROID(input.shape,0.001).SDO_POINT.Y COORD_Y,

SDO_GEOM.SDO_INTERSECTION(input.shape, target.shape, 0.005) SHAPE

FROM

SCPX.VGIS_IM_FIELD_COLLECT_PT input,

VGIS_GD_MAP_INDEX_AREA_GEO1 target

WHERE

SDO_GEOM.SDO_AREA(SDO_GEOM.SDO_INTERSECTION

(input.shape, target.shape, 0.005),0.005) is not null;

Spatial Views – Spatial Analytics

Tracy McLane. Innovative Approaches to Modeling GPS/GNSS Construction Data with

Oracle Spatial and Graph. Oracle BIWA and Oracle Spatial Summit 2015. January 27 - 29,

2015. San Francisco, California.

I. Minimize the number of spatial records / features for the database (decreases storage size)

Dissolve on Layer name, using multipart option Break the features back into single part

**Densify features from CAD like roads, rivers, pond, basin or any features that is comprised of arcs, b-spline curves or other complex elements II. Use Identity to create more uniform size of features for the database

More uniform geometry allows Oracle R Tree spatial indexing to better improve performance and refresh times

III. Attribute indexing on:

Attributes used in attribute or spatial view criteria Attributes used as primary or foreign key Attributes used for map symbology
