This group was really hard to find trying to navigate the website. The only way I found it was here, in the forum.

I have been trying to open the layer in ArcGIS Desktop (10) and it doesn't seem to work. Are they not available to be used in 10.0?

Re: Welcome to the Landscape Layers forum

AndreaBolks — Thu, 18 Jul 2013 13:52:30 GMT

OK- I now see that yes you need 10.1 to open in ArcMap. Why can I not open the maps in online though? I am part of the EPA's Online Organization but still cannot access the content and I am not sure why?

The USA Soil Map Units service is only visible in the web interface at large scales because of the detail of the data. If you are having trouble displaying a service, try zooming in and see if anything appears. If this does not work or you have problems accessing any of the landscape services please continue to let us know.

I want to add four layers to a topographical basemap. I have added three layers successfully--roads, railroads, and waterways--so that all the layers and the basemap can be seen at once; that is, roads, railroads, waterways, and topography are all visible on one map. I want to also add a layer of transmissions lines, but the ESRI transmission lines layer is not transparent like the other layers. When I add that layer, it covers the basemap and all the other layers so that they are not visible.

Is there a transmission lines layer that allows you to see through to the basemap and other layers, or can the transmission lines layer somehow be made transparent so that the basemap and other layers can be seen?

[INDENT]The USA_Transmission_Lines layer you have added to your map is an image service layer, which comes from a raster layer source. In ArcMap, in order to "see through" the raster you will need to change the way the transmission lines image/raster layer is symbolized.

The zero values should be set as background values, and then the color ramp should be inverted. First, in the layer properties, in the Symbology tab, check on the option to Display Background Value: 0 (zero) as 'No Color', then under 'Stretch, check on the Invert option and click OK.

If this doesn't fully meet your needs, you can also apply transparency to the layer properties, within the 'Display' tab.[/INDENT]

Thank you very much replying. I found where I could adjust the transparency yesterday, and that solved my problem.

Hi,

I am attempting to load the USA Soil Map Units (NRCS SSURGO dataset) in ArcGIS 10.1 and am having problems. After clicking "Add", ArcMap thinks for a minute and then nothing happens. I am zoomed in to a very large scale (small area) but the data doesn't even show in the layers section. It seems like a bunch of people are having the same problem and it may be available using a certain format, but not through this one. Any help would be greatly appreciated.

Hi Greg,

I tried to reproduce the results from the steps as you stated using ArcGIS 10.1, but I was able to see the layer in the table of contents, the data was visible at a large scale (visible out to 1:100,000), and the data was queryable. Please let us know if you are still experiencing a problem. The service appears to be working in ArcGIS Desktop 10.1, as well as 10.2.2.

Thank you,

It would be nice if there was a link from the forum to the Landscape Layers web page.

Please sort your posts so the most recent are at the top of the page...tnx

The Landscape Layers are in a group in ArcGIS Online here and also available through the Living Atlas of the World within the Landscape theme.

Hello! Is there any want to get a tabular list of all the Esri Landscape Layers that are available with a basic description of each? I'm basically hoping for a csv dump that I can use to explore the possibilities.

Thanks very much!

Madeline

Re: Welcome to the Landscape Layers forum

CharlieFrye — Mon, 23 Feb 2015 16:47:20 GMT

Here is a link to a tabular listing of Esri Landscape Layers as of today; noting there are plans to add more soon: Landscape Services in Living Atlas.pdf - Box

Also note there is a link at the bottom of the page to the ArcGIS Online group that contains all of these layers.

Each layer in the list is hyperlinked to a corresponding ArcGIS Online content item, or to an ArcGIS Online search result when there are multiple layers that match the name. For instance the latter scenario would include when we have an image service (raster) and a dynamic map service (vector) for the same topic.

The descriptions in the content items introduce the layer, explain a little bit about the characteristics of the underlying data that are relevant for ArcGIS and for landscape applications. For instance, it was often necessary to process the data in order to transform it into a form that would be immediately useful in ArcGIS. Please let us know if we've failed to provide anything critical to successfully using any of these layers.

Hello Charlie,

Thanks for the reply. The tabular list of layers was very handy for us. I see that that link has expired, and am wondering if any new layers have been added since I grabbed a copy. Do you all have plans to regularly update that list and keep it in a standard place? If so, where is that? If not, do you have a more up to date list that you could post now?

I have one other question. I'd really like to access the landscape analysis layers via arcpy, but I suspect this is not possible. As this thread says, "you cannot make a connection from Python to ArcGIS.com." Is this indeed the case? If so, do you know if anyone has created a script tool that allows people to iterate through subsections of a geography until the entire area has been processed as a way to get around the analysis limitations of the landscape layers? If nothing like this exists, I will probably write it myself as we are working on a project that covers most of the western conterminous states and would like to avoid downloading rasters when your excellent services are avaiable.

Thanks very much for you help,

Madeline

Re: Welcome to the Landscape Layers forum

Good news on both fronts. There is new content in the landscape layers, however it has not been announced yet, and I'd rather not do that here. I will be updating the PDF, likely in early April, as we have some additional content that will be done in the next week or two as well.

On the Python question, you can use Python to access any public service (meaning if you know the URL to the ArcGIS server folder, it's public). The main consideration is some services are authenticated, and therefore require a token to access. Then it is only a matter of what kind of service is being accessed. I will contact you separately to share this.

Thank you Charlie! I'm looking forward to the new content annoucements!

Hi Madeline,

I’ve enclosed two scripts (not sure how GeoNet will handle enclosures)…

The GeoenrichPoly script uses landscape image services by summarizing them within a polygon. The SupplyDemand script shows how to use feature services, and represents a better formalization of coding practices by separating the getToken assertJsonSuccess functions.

It took about 12 weeks to figure all this out while working with the development team here in Redlands. The point is that this is fairly advanced Python coding, particularly using the HTTPLib, and may take a few days to work through.

Both are provided as is, with the expectation that you will have a username and password from an organization account to use in the variables that are currently defined as: userName = "" & passWord = "".

Let me know if you have questions,

Charlie

Hello Charlie! This group of Landscape Layers is great! I have a few questions in regards to automation. I've come across the "Extract Landscape Source Data" tool here available with the Mapping Service:

http://www.arcgis.com/home/item.html?id=06f9e2f5f7ee4efcae283ea389bded15

I would love to automate this and develop a python script to iterate through and extract a series of desired layers.

I created a simple python script but it fails because credentials (My AGO Organizational account) is not included anywhere:

# Import arcpy module

import arcpy

# Load required toolboxes

arcpy.ImportToolbox("http://landscape1.arcgis.com/arcgis/services;Tools/ExtractData")

# Local variables:

StudyArea = "L:\\temp\\StudyAreas.gdb\\StudyArea"

The following error occurs because I believe, of the lack of credentials

Traceback (most recent call last):

File "L:\Tools\EnE_Python_Tools\Land.py", line 13, in <module>

arcpy.ImportToolbox("http://landscape1.arcgis.com/arcgis/Tools/ExtractData")

File "C:\Program Files (x86)\ArcGIS\Desktop10.3\ArcPy\arcpy\__init__.py", line 124, in ImportToolbox

return import_toolbox(input_file, module_name)

File "C:\Program Files (x86)\ArcGIS\Desktop10.3\ArcPy\arcpy\toolbox_code.py", line 434, in import_toolbox

toolbox = gp.createObject("Toolbox", tbxfile)

File "C:\Program Files (x86)\ArcGIS\Desktop10.3\ArcPy\arcpy\geoprocessing\_base.py", line 379, in createObject

self._gp.CreateObject(*gp_fixargs(args, True)))

IOError: The toolbox file http://landscape1.arcgis.com/arcgis/Tools/ExtractData was not found.

1. How would I in python supply these credentials.

2. I note some more detailed scripts you've offered on this site such as the Supply Demand Script. That script seems to generate an access token and specfically iterates through items in the Landscape dataset as a Feature Cursor.

Not sure if the latter would work as in this case Extract Data does exactly what I need (depending on the feature limits). I would want to actually clip to my polygon extent (unless I modified something like the Supply Demand tool to extract features, to get around the limit, then executed the clip locally after the fact.

Any thoughts? Thanks!

Hi Greg,

Below are examples for doing what you need. Depending on whether you are accessing image services or feature and dynamic map services, the workflow differs.

Image services, which requires using the MakeImageServerLayer tool:

#-------------------------------------------------------------------------------

# Name: Access Living Atlas Image Service Example ArcPy Python Script

# Purpose: Show how to us image services in scripting

# Created: 07/15/2015

#-------------------------------------------------------------------------------

# Import arcpy module

import arcpy

arcpy.CheckOutExtension("Spatial")

from arcpy import env

from arcpy.sa import *

import os.path

# set geoprocessing environment settings

# including workspace, extent (from existing study area dataset) and coordinate system

env.overwriteOutput = True

env.workspace = r"D:\TestFs"

env.extent = r"D:\TestFs\ImageLayerByPolygon.gdb\studyArea"

env.outputCoordinateSystem = arcpy.SpatialReference(54009) #using WKID for Mollweide, for area-based analysis

# create connection file to esri landscape server from above parametersservername = "landscape7"

userName = "" #supply your own ArcGIS Online Organization account credentials

passWord = ""

servername = "landscape7"

d = arcpy.mapping.CreateGISServerConnectionFile("USE_GIS_SERVICES", arcpy.env.scratchFolder,

servername + ".ags", "http://" + servername + ".arcgis.com/arcgis/rest/services",

"ARCGIS_SERVER", '', '', userName, passWord, "SAVE_USERNAME")

# set up image layer from the landscape server connection, and get its spatial reference

imageservicename = "World_Landforms_Improved_Hammond_Method"

imageService = os.path.join(arcpy.env.scratchFolder, servername, imageservicename + ".ImageServer")

# Create the Image Service Layer

inputImageLayer = arcpy.MakeImageServerLayer_management(imageService,"imageLayer", "")

# Example of using in a subsequent process

outputrastername = "Landforms"

output = r"D:\TestFs\Results.gdb"

pr = arcpy.CopyRaster_management (inputImageLayer, output+"//"+ outputrastername)
