Maximizing Spatial Analysis for your Business

Steve KoppMark Smithgall

Overview

• Finding the best place (Bakken oil leases)- Understanding site selection / suitability modeling- ArcGIS Online (GeoPlanner)- Analysis in ArcGIS Pro

• Surface Analysis with hosted web services (rig site evaluation)- ArcMap / ArcGlobe- ArcGIS Online- Web AppBuilder

• Q&A

Finding the best place• Find the best leases

• Exploration - basin and play analysis

• Locating optimal pipeline corridors

• Where to site a new gas station

Reality GIS layers Best leases

Binary suitability models

• Use for simple problems- Like a query

• Classify layers as good (1) or bad (0)

Best Lease = Lease% &Land restrictions &Ease of delivery

• Advantages:- Quick to build- Easy to build and explain- Works well with vector or raster data

• Disadvantages:- No “next-best” sites - All layers have same importance- All good values have same importance

Weighted suitability models

• Use for complex problems

• Classify layers into suitability 1–9 - Weight and add together:

Oil = (Lease%* 0.5) + (Restrictions * 0.3) + (Delivery * 0.2)

• Advantages:- Flexible for exploring alternatives- All values have relative importance- All layers have relative importance

• Disadvantages:- Design and construction requires planning

Feedback

Design the model

• This is normally a team activity• Domain experts, decision makers

• Define the problem• Find the best oil leases

• Determine how to measure• Need information about leases (availability, %, history)• Need landscape information• Need delivery information

• Obtain necessary data

Define the Measures

• Determine significant layers to the phenomenon being modeled

• Reclassify the values of each layer into a relative scale- Use relevant class breaks- or Rescale By Function tool

• Weight the importance of each layer

• Add the layers together

• Run and Revise the model

Define a scale of suitability

• Define a scale for suitability- Typically 1 to 9 (worst to best)- Reclassify layer values into relevant classes- Assign suitability value to each class- Use the same scale for all layers in the model

DemoFinding the best placewith the Weighted Overlay tool

Weighted Overlay AnalysisArcGIS Desktop Weighted Overlay tool

• Traditional approach where a GIS Analyst constructs a model for their own use• Often presented in a meeting scenario where the analyst drives the software while

others provide input• Easy to change class breaks, class weights, and layers weights• Analysis most often performed at full resolution (can be screen resolution)• Analysis result is a file on disk and can be used in further analysis or shared

Weighted Overlay AnalysisArcGIS Online GeoPlanner

• New approach allowing the GIS Analyst to configure a web application for many to use• Allows stakeholders to explore the data and their model preferences interactively• Class breaks are defined by analyst during application construction• Easy UI for users to change class weights and layer weights• Integrated graphing tools for exploring model results• Analysis most often performed at screen resolution (can be full resolution)• Analysis result temporary and only lives within the application (changing in future)• Part of a comprehensive GeoDesign application

Weighted Overlay AnalysisDifferent implementations for different purposes

Terrain Analysiswith Web Services

Surface Analysis using Web ServicesDrilling Rig Site Evaluation

• Who can see the rig?

• If there is a spill, where will go?

Elevation Analysis Services are available across the platform

• Ready to Use Services in ArcGIS Desktop

• ArcGIS Online Analytics

• Web App Builder

• REST endpoints for developers

Uses ArcGIS Online global elevation and geoprocessing services

Can be configured to run on your data and your server

• Profile- Explore elevation along a path- Also available as a web app template, Desktop Add In ,

and Web AppBuilder widget

• SummarizeElevation- Calculate summary statistics including elevation, slope,

and aspect for user specified features

• Viewshed- Identify visible areas based on user provided

observation points

Terrain analysis tools

• TraceDownstream- Determine the downstream path of water across the landscape from a user specified point- Where does water flow to?

• Watershed- Determine the upslope area that contributes flow above each user specified point. - Where does the water come from?

Hydrologic analysis tools

Ready-To-Use Services in ArcGIS Desktop

• Esri hosted analysis on Esri hosted data- simplify job of GIS Professionals- can be used in models and scripts

just like any other tool- combine to create new solutions

- extend spatial analysis to a much broader audience

Analysis in the ArcGIS.com Map Viewer

• Expanding the use of spatial analysis throughout your organization• Analysis of ArcGIS Online data

- Esri provided (demographics, landscape)- User provided (my project data, geoRSS, CSV, etc)

• Coarse grained, high-level solutions• Now includes surface analysis tools
