Repairing Broken Data Sources cont. & connecting to U:\GIS_IDFG.gdb

The IFWIS shop has migrated all of our most useful GIS data to new geodatabases that will live in each region.  What does that mean?  That means that your GIS projects should be much faster to build and work with because regional users will be requesting data from a local geodatabase instead of a geodatabase sitting at headquarters.  The layers in the LayerFetcher tool are now all referencing the new geodatabase.  Within each region, the geodatabase is located at U:\GIS_IDFG.gdb.  Instead of referencing K:\IFWIS\SDE_Layers\SDE_Vector.sde to repair broken data sources, you should reference U:\GIS_IDFG.gdb.

To elaborate a little on the original 'Repairing Broken Data Sources' blog post, you can also repair multiple broken data sources in ArcMap.

In ArcMap, right-click a layer with a broken data source --> Data --> Repair Data Source...

Navigate to the U drive:

If you don't see the U drive in your Data Source directory, you need to make a new connection.  In the Data Source dialog, click the 'Connect to Folder' icon and navigate to the U drive.  In the GIS_IDFG.gdb, navigate to the corresponding feature class.  For instance, if you are repairing the 'Major Rivers' layer, navigate to 'Hydro_Stream_Idaho'. How did I know which feature class to navigate to?  You can figure out the name of the feature class you are looking for by looking at the 'Source' tab of the 'Layer Properties' window of the broken layer.

‘Repair Data Source’ may repair multiple layers if the matching feature class in the new geodatabase has the same name.  For instance, the wilderness areas layer will not be repaired because the original feature class used to created the layer was called ‘wilderness’ and the new feature class is called ‘wilderness areas’.

After a data source has been repaired you may receive drawing errors such as:

What do all those errors mean?!?  While we were creating the new GIS_IDFG.gdb for the regions, we thought it was also a good opportunity to update some of the data.  Consequently, some of the field names have changed.  So, after the data source is repaired old definition queries and label expression may cause the layer or its labels to not draw.  You have two options, you can edit the definition queries and label expressions using the proper field names OR you can remove the layer entirely and re-add the layer using the LayerFetcher.  

Here are a couple of examples of errors cause by legacy queries and expressions and how to fix them. 

The 'Hydrography (Idaho Only), Major Rivers' layer has a definition query of 

In the new 'Hydro_Stream_Idaho' feature class the length field is called Shape_Length and the LLID fields is a text field instead of a numeric field.  The definition query must now read Shape_Length > 50000 OR LLID = '1149345461224'.

The 'Geographic Names (w/o Hydro)' layer has a definition query of TYPE <> 'lake' AND TYPE <> 'reservoir' AND TYPE <> 'stream'.  In the new GNIS feature class, the type field is now called 'class'.

The label expression for the geographic names layer is [NAME].  In the new GNIS feature class, the name field is called 'Feature_Na'.

Windfarm: USGS Releases Interactive Map of U.S. Wind Turbines

From the USGS website: "To remedy the lack of information, the USGS created this publicly available national dataset and interactive mapping application of wind turbines.  This dataset is built with publicly available data, as well as searching for and identifying individual wind turbines using satellite imagery. The locations of all wind turbines, including the publicly available datasets, were visually verified with high-resolution remote imagery to within plus or minus 10 meters."

Display BLM PLSS (township, range, section) & USGS Quadrangle data in Google Earth using Earth Survey Tools

Have you ever been looking for a feature in Google Earth & thought, boy this would be so much easier if I could search for it by township, range, section.  Well, now you can!  Just use the Earth Survey Plugin (ESPlugin).

What all does the Earth Survey Plugin have to offer:

  • Section Geocoder: search by point or township,range, section. Link to the BLM General Land Office records webpage which provides "live access to Federal land conveyance records for the Public Land States, including image access to more than five million Federal land title records issued between 1820 and the present. [They] also have images related to survey plats and field notes, dating back to 1810."
  • Address Geocoder: get address information for placemarks and add, customize, and save placemark data.
  • Overlays: drive-time (5, 10, and 15 minute) polygons; BLM townships, principal meridians, and special surveys; USGS quadrangle index and topo maps.
  • Layers: borders (counties, states, etc.), roads, buildings (not available in all cities), trees (not available in all cities), and terrain

Geospatial PDF?!? How to Create a Geospatially Aware PDF

 

Yes, it is true!  You can make a PDF map spatially aware (aka georeferenced).  Geospatial PDF’s allow users to obtain latitude and longitude coordinates, turn data layers on and off, view a selected features attributes, and to query and highlight data.  This tutorial will explain how you create a spatially aware PDF map from ESRI ArcMap.  Just follow these easy steps!

1) Obtain the latest version of Adobe Reader (for free) at: http://get.adobe.com/reader/. NOTE: This tutorial uses Adobe Reader 10 so if you are using a later or newer version, some of the menus, etc. may be different.

2) Once you have created your map in ArcMap, select Export Map… from the File menu. Choose PDF from the ‘Save as type:” dialog box. If it is not already expanded, expand the Options menu at the bottom of the Export Map dialog box. Select the Advanced tab.  In the Layers and Attributes drop-down menu select ‘Export PDF Layers and Feature Attributes’. Also check the box in front of ‘Export Map Georeference Information’. 

 

3) Open your exported map in Adobe Reader.  Add the Model Tree to the Navigation Pane running down the left side of the Reader by right-clicking the panel.

 

4) Start exploring! 

 

 

TOGGLE LAYERS ON & OFF

Click on the Layers icon in the Navigation Panel.

 

 

You can turn layers/labels on or off by clicking the Eye icon to the left of a group of or individual layers.

 

VIEW ATTRIBUTE DATA

Click on the Model Tree icon in the Navigation Panel.

 

Select a feature from the list to see its attributes (NOTE: These are the same attributes that appear in the attribute tables in ArcMap. If there is a field that is turned off in your ArcMap attribute table, it will also not appear in the PDF). The feature will also be highlighted in the map.

 

You can also select a feature with your mouse on the map to view its attributes in the Model tree. To do so, you must have the Object Data tool on. To turn this tool on: from the Edit menu, select Analysis, and then Object Data Tool.

 

Finally, using the Find tool is also a simple way to query for data.  Simply type the name of the feature into the Find tool or Advanced Search search box.  If there is more than one feature that meets the criteria, it will be listed on the screen.  To see the attributes of a specific feature, select it from the search results list.

 

FIND LATITUDE AND LONGITUDE COORDINATES

To turn this tool on: from the Edit menu, select Analysis, and then Geospatial Location Tool. The location of the cursor while be shown in a text box at the bottom of the screen.

 

HELPFUL FACTS AND TIPS FROM THE ArcGIS RESOURCES WEBPAGE

http://resources.arcgis.com/en/help/main/10.1/index.html#/Exporting_to_PDF/00sm00000007000000/

· Each data frame will have its own folder in the tree view of the PDF that contains all the layers and the data frame graphics (neatline, background) associated with it.

· Text, picture, or north arrow elements added to a layout become part of a layer called Other. It contains all the graphics and marginalia that are not part of a data frame.

· Each group layer will be represented as a folder in the tree view, and the contents of the group layer will be presented within the group layer.

· Layers that cause rasterization, such as transparent layers, or layers that use a picture fill symbology consolidate all the layers below them into a single layer with the name Image.

· If a layer contains picture marker or picture fill symbology, use the option Vectorize picture markers/fills, found on the Format tab of the Options panel. This prevents rasterization of layers below picture markers and fills.

· Raster layers, such as orthophotos, consolidate all layers below them into a single Image layer. Place raster layers lower in the ArcMap table of contents to avoid this problem.

· Graphic or text elements added to the data frame's default graphics layer from data view become a layer called <Default>. These are displayed above the layers in the data frame. If multiple annotation groups exist (check this on the Drawing > Active Annotation Target menu command on the Draw toolbar) and their contents are in the data view, each individual annotation group becomes a separate layer above the <Default> layer. This is a good way to add focus areas or graphics that emphasize or mask certain features in the data view.

· Backgrounds or drop shadows added to the data frame may become separate graphic elements and may be rendered multiple times as graphics. For example, if a data frame has a colored background, and the layout has a different colored background, the data frame's background may be rendered once to the data frame's Graphics or ArcGIS Layer and again to the layout's Graphics layer or ArcGIS Layer.

· Dynamic labels (not using annotation) in each data frame are rendered separately as part of a layer called Labels.

· Geodatabase annotation is displayed as a separate layer in the PDF. Map annotation is consolidated into the layer for the annotation group in which it belongs.

· When labels are converted to annotation, they are automatically placed in their own named annotation group and render separately from the<Default> group.

· Data frames and other layout elements are rendered in draw order when exported to PDF. Therefore, the topmost layout element in the map is the first element in the resultant PDF table of contents. Use the Bring Forward and Send Backward commands from the Draw toolbar to change the draw order of layout elements.

ENJOY!!!

ArcMap 10.1 - Edit the Service Layer Credit

In ArcMap 10.1 if you add a basemap to a mapping project, a service layer credit for the basemap (or any dataset streamed as a service from ArcGIS online) automatically shows up in the Layout View. 

The position, font, color, size, etc. of the service layer credit may not be to your liking. To edit the service layer credit in Layout View, go to the Insert menu, select Dynamic Text --> Service Layer Credits.  The credits textbox will become editable/moveable.  You cannot just delete the credits textbox. Due to licensing agreements, it will just show up again. 

 

 

 

How to Load a Boundary (Track) File into a GPS Unit

 

Let’s say you would like to upload Game Management Unit 1 to your GPS. 

1) Download the Game Management Units KML from the IFWIS Open Data page, https://fishandgame.idaho.gov/ifwis/portal/opendata.

2) Open the KML in Google Earth. Right-click “1” in the gmu features list. Select “Save Place As…”

3) Save the feature as a KML (not a KMZ).

4) Convert the KML to a GPX file.  There are many open-source software options.  I like KML2GPX.exe (download from https://groups.google.com/forum/?fromgroups=#!msg/kml-support-getting-started/5K7vcIGUz6s/_EvtN-YqXuwJ) and GPSBabel (download from http://www.gpsbabel.org/).

5) Upload the GPX file as a track to your GPS.  NOTE: for those GPS units with smaller data storage space or without a data storage card the track may be too large to upload without simplifying.  Using GPSBabel, you can apply a “Filter” to the Routes & Tracks to simplify the boundary.  For units such as the etrex Vista Cx, I know that the track point upload limit is 500 (otherwise it will give you a message that says “track truncated”. The Minnesota DNRGPS Application also works well for uploading data but I have not found a way to simplify the track using this software (http://www.dnr.state.mn.us/mis/gis/DNRGPS/DNRGPS.html). 

There are many different tactics for completing this process but these are the steps that have given me the least amounts of difficulties for a number of different Garmin GPS units.  These steps have not been tested on Magellan, Lowrance, TomTom, etc.

Do you have another method that works better for you?  Please share in the comment below!
