Submitted by Tim Patterson, Division of State Lands -

Greetings from DSL:

This is a heads up for GIS Mangers using

"State Lands Parcels from FTSLI (large)"  DEP.STATE_LANDS_PARCELS_LARGE
and
"State Lands Parcels from FTSLI (small)"  DEP.STATE_LANDS_PARCELS_SMALL

These two data sets will be replaced by the new=20

"State Land Records" DEP.DSL_PARCEL_COMPOSITE

The new "State Land Records" polygon data is updated weekly in SDE and
monthly on the FTP site with enhanced and expanded attribute data =
including
if a parcel is Acquired, Disposed of or Encumbered.  The XML metadata =
include
detailed attribute descriptions however; the BIS-DEP metadata format
suppresses important attribute information in Data Miner and the GeoData =
web
pages.  I would suggest reading the metadata with ArcCatalog.

We will keep the both the old and new versions available until April 29, =
2005
at which time the old  "State Lands Parcels from FTSLI" versions will be
deleted.  If you need more time to point your applications to the new =
data,
please call me.


Submitted by Gary Cook, Beaches and Coastal Resources -

Over here at Beaches we are getting ready to release our aerial =
photography
of Escambia, Santa Rosa, Okaloosa, Walton, Bay, Gulf and Franklin =
Counties.
This was flown before hurricane Ivan.  The photography ground control
targeting schedule got delayed because the survey crews were busy with =
all
the storms we had last summer.  This held up delivery of the final =
product by
the company that processes our images.  Metadata will be created this =
week
and we should be ready to transfer everything over to SDE next week.  =
When
this is accomplished our IMS site will also be updated with the new
photography.  Now on to the SW region, Pinellas to Collier, hopefully by =
late
summer unless we get multiple storms again.

We are also processing Lidar data that the Federal Government collected =
early
last year and repeated late last year.  This pre and post storm =
information
should provide an excellent source of detecting change on the coast.  =
Since
this was a US Army Corps of Engineers and NOAA Coastal Service Center
collaborative this Lidar is only along the immediate coastline.  1.5
kilometer inland and 1KM offshore.  I'm comparing it to our information =
to
see how accurate it is since no ground control was done by them before =
or
during the flights.  This takes awhile, the total of XYZ files alone is =
45gb.
Each file has around 3.5 million points.  ArcView really doesn't like =
files
this large and doesn't accept any variation in what format the file must =
be
in to create the points, so we are using Surfer to extract profiles and
contour maps.  Corpscon makes short work of converting Lat/Lon to State =
Plane
and meters to feet.  After all this work the 3D surface created is =
awesome. =20


Submitted by Joe North, Bureau of Watershed Management -

The Bureau of Watershed Management's GIS subsection supports a number of
program areas: Impaired Waters - Total Maximum Daily Load, Status and =
Trend
water quality monitoring, Outstanding Florida Waters, Everglades and the =
319
Grant - Non Point Source programs. =20

Most notable of our recent activities are two concurrent efforts aimed =
at
facilitating the creation of a base population of water quality =
monitoring
stations that generate sampling results that are used by the TMDL =
program in
the assignment of Impaired Waters Rule classifications.  These include:
  =20
	1.	The creation of a population of event themes based on 1:24K
National Hydrologic Dataset (NHD) features that equate to Total Maximum =
Daily
Load program assessment units commonly known as WBID's.
	2.	The assignment of STORET water quality sampling stations to
NHD features (reaches) through an attribution process and assignment of
locational confidence levels based on the availability of descriptive
information contained in the STORET database.


Submitted by Linc Clay, BIS/GIS -

ESRI has announced that ArcGIS 9.1 will be shipping shortly.  Here is =
our
rough migration timetable.

	ArcGIS 9.1 Desktop Migration - late Q3/early Q4 of calendar 2005

	ArcIMS 9.1 Internet Mapping Migration - late Q3 of calendar 2005

	ArcSDE 9.1 Spatial Data Service Migration - mid to late Q4 of
calendar 2005

The 2004 DOQQs are being processed by FREAC (mosaiced, projected, and =
clipped
to the quarter-quad grid).  We expect to have them (less SFWMD which has =
not
been completed yet) by the end of Q2 of calendar 2005.  As the 2004 =
imagery
is inserted into ArcSDE, the 1994 DOQQs will be removed to make room.  =
The
1994 DOQQs will still be accessible in a file-based format.
