## SDTS

**Raster Profile with BIIF Extension**

**A Profile Under Development**

## Raster Profile with BIIF Extension

**New Version includes BIIF**
**Harmonization effort between USGS and NIMA**
**Abbreviation is SRPBE**
**Final Stages of Development**
**not ratified, but technically stable**
**Seeking FGDC approval**
**Changes made to ANSI draft SDTS to better support raster; profile uses these**

## SRPBE Scope

**Georeferenced**
**known relationship to latitude and longitude**
**unspecified is allowed**
**Images and Grids (2-dim only)**
**Not Permitted**
**Vector data **_**not**_** allowed**
**N-dimensional raster **_**not**_** allowed**
**Labeled rasters **_**not **_**allowed**

## Raster Profile

**Raster Spatial Objects**
**Pixels & Grid Cells - smallest units of a raster**
**Images and Grids - aggregations of pixels and grid cells**
**Layers or Bands - themes or color bands**

## Raster Profile

**Raster Object restrictions**
**A “Raster Object” consists of one or more raster layers with the same horizontal spatial extent and number of rows/columns.**
**A “Raster Object” is represented by one Raster Definition Module record.**
**One transfer can have multiple raster objects**

## Raster Profile

***External reference system***

**SDTS**

**SPCS**

**UTM / UPS**

**Other**

**Unknown**

**    ****Lat / Long**

**All options are permitted. Raster data is not required to be**
**reprojected or even rectified.  Warped grids are allowed.**

## Raster Profile

**Internal Spatial Reference & Scan Reference**
**Either scaling and translation to go from internal to external or use Registration module**
**All layers in a **_**raster object**_** must use the same internal and scan reference system and have the same resolution**
**Each layer of a multi-layer raster must be coincident**
**If internal reference systems differs or resolution differs, then  the layers must go in a different raster objects**

## Raster Profile

**Object Modules**
**Each raster has its own set of one or more Cell modules**
**Cells can be interleaved by layer or by pixel; interleaving by line is not permitted**
**Scan origin is highly recommended to be upper left**
**Scan pattern is highly recommended to be by row**

## Raster Profile

**Shall be 4-character standardized**
**Use primary field mnemonic**
**IDEN (Identification)**
**RSDF (Raster Definition)**
**More than 1 Cell Module allowed**
**Cnnn (nnn changes with each new module)**

**Module Names (same as TVP)**

**10/01/93**

## Raster Profile Annex Options

**BIIF**
**an alternate format for image data**
**has advanced visualization controls**
**suite of compression techniques**
**Color Index Module**
**allows color palette transfer**
**used for display purposes**
**(Not required to be implemented)**

## Raster Profile Timeline

**Effort to Modify draft RP for BIIF**
**Joint USGS and NIMA Effort June 96**
**Initial Draft for FGDC Internal Review**
**To the Standards Working Group July 97**
**Public Comment Period**
**to be announced by FGDC**
