## Update on Spatial and GIO Related Issues

## Integration of key Spatial Water Datasets

**National Elevation Dataset **
**(NED)**

**National Hydrography Dataset**
**(NHD)**

**Watershed Boundary Dataset(WBD)**

**NED-Hydrology (EDNA)**

## NED

**NED**
**National Elevation Dataset**

**Notes:**
NED National Elevation Dataset
Nationwide seamless 30-meter (1-sec) resolution.
Availabvle for the conterminous US; available for download 10megabytes at a time

## Stage 1

**EDNA [alias NED-H]**

** ****2101 HUCs processed**

**1644 HUCs reviewed**

## 5000pixels

- 2 sq.miles!

**Notes:**
Exaple of “reach catchments” that are produce by Stage 1 NED-H work.
This is in the Austin, TX area.

## Slide 8

## COMPLETED FALL 2002

**Hydro Standard **
**Work Group**

**Notes:**
New workgroup formed to develop a “National Hydro Data Content Standard”

## Current version can be found at . . . .

**Notes:**
You can get the latest version of the HUC Guideline here.

## DRAFT Attribute Scheme (PAT)

- (karst, interbasin transfer, etc)

**Notes:**
Notice the change to attributes.  HU_MOD allowws for consideration of karst

## proposed:

**Subcommittee review**** **
** **

**currently:**
**NRCS certification**

**Notes:**
NRCS certification no longer appropriate; review & compliance letter should come from interaqency Subcommittee

**FGDC**
**HUC Interagency**
**Guideline**

**Notes:**
April 20, 2000 Guideline Workgroup produce initial version of “Unified (interagency) Guidelines.  These are now in review by the Subcommittee and FGDC.

## STAGE 1

**EDNA [alias NED-H]**

**STAGE 1**

**Notes:**
NED-H now call EDNA (Elevation derivative for National apllications).
This is status as of Dec’00.  Everything but FL, TX, and LA is done.  
Caution of using this “research” dataset.  It is still “a work in progress”
