SEPM X-Raster

Specifications

Raster import / export for Smallworld

With SEPM X-Raster, multiple raster files can be imported together into Smallworld in one step. The export function allows the export of Smallworld data as raster tiles in different file formats. Current SEPM releases also support Smallworld 6.x environments.

Raster import

Selection of raster files, target collection and target geometry

Raster import starts with your file selection, a target collection and target geometry. X-Raster applies Smallworld raster import parameters, optional transforms and georeferencing, then loads the imagery into your GIS.

Import

The advantages raster import gives you

1. 01

   Adjustable parameters

   All parameters of the underlying Smallworld raster import functions can be set from the X-Raster user interface.

2. 02

   Additional parameters

   Translations in the x/y direction and mirror operations around the x- or y-axis can be configured in the UI.

3. 03

   Registration information

   World files (TFW) are parsed to position the raster data in the correct map location.

4. 04

   GeoTIFF

   Georeferencing information can be extracted from GeoTIFF files when it represents an affine transformation.

5. 05

   Preview feature

   Outlines and file names are displayed as previews before the import is committed.

6. 06

   Update feature

   Existing raster objects can be updated with fresh raster data without rebuilding the workflow from scratch.

Raster export applications

Why teams export from Smallworld

Raster export delivers map data to recipients who do not receive vector data, archives data as-of a specific date, stores scanned plans as georeferenced raster files after GIS processing, and powers individual information solutions built on Smallworld.

Smallworld data

Exported raster section

• Raster-only delivery

  Share map content as imagery when partners or regulators cannot accept vector deliverables.

• Point-in-time archive

  Freeze the visible map state on a given date as raster tiles for compliance or historical reference.

• Scanned plan storage

  Keep processed paper plans as georeferenced raster files inside your GIS landscape.

• Custom solutions

  Embed X-Raster as an engine in bespoke export or download workflows — for example TIFF download from a web application.

Export

The advantages raster export gives you

1. 01

   Adjustable parameters

   Tile size and pixel size in the x- and y-directions are adjustable to match the target scale and file size.

2. 02

   Adjustable margin

   Extend the rendered area beyond the tile edge so labels and symbols are not clipped at boundaries.

3. 03

   Aggregation of tiles

   Adjacent tiles can be combined into larger raster files for simpler handoff or fewer files on disk.

4. 04

   Registration information

   A TFW world file is created automatically so imagery can be positioned geographically in the target system.

5. 05

   Project information

   ArcPad and ArcExplorer project files can be generated when field teams need ready-made mobile projects.

6. 06

   Use it as an engine

   Run headless export through Magik for automated jobs — for example a “download to TIFF” feature in a web application.
