1. Shawn Stiver ARC Fall Semester, 2016 Geography 385 GIS For The Web
This template can be used as a starter file for presenting training materials in a group setting.
Sections
Right-click on a slide to add sections. Sections can help to organize your slides or facilitate collaboration between multiple authors.
Notes
Use the Notes section for delivery notes or to provide additional details for the audience. View these notes in Presentation View during your presentation.
Keep in mind the font size (important for accessibility, visibility, videotaping, and online production)
Coordinated colors
Pay particular attention to the graphs, charts, and text boxes.
Consider that attendees will print in black and white or grayscale. Run a test print to make sure your colors work when printed in pure black and white and grayscale.
Graphics, tables, and graphs
Keep it simple: If possible, use consistent, non-distracting styles and colors.
Label all graphs and tables.
Northern California Commercial Cannabis Cultivation Laws – An Interactive Map Using ESRI ArcGIS Online

ARC Fall Semester, 2016

GIS For The Web

2. Project Concept and Goals:
California has recently approved the consumption of cannabis for recreational use.
Commercial cannabis services are subject to far more restrictive ordinances.
These ordinances vary from county to county, sometimes from city to city.
This project aims to provide a quick guide to services allowable within northern California counties, areas and parcels where commercial cultivation is allowed within the city of Sacramento, and links on where to
obtain more information.
Give a brief overview of the presentation. Describe the major focus of the presentation and why it is important.
Introduce each of the major topics.
To provide a road map for the audience, you can repeat this Overview slide throughout the presentation, highlighting the particular topic you will discuss next.

3. Source Data: Northern California Counties
City of Sacramento Boundaries
City of Sacramento Zoning
City of Sacramento Parcel Data
City of Sacramento Schools and Parks
This is another option for an Overview slides using transitions.
City of Sacramento Zoning
Northern California Counties

4. Data Preparation Data Pre-Processing
Additional attribute columns added to reflect service status by county, legal zoning status, and legal parcel status.
Additional County Attribute Columns
Geoprocessing
Buffers created to show zones surrounding schools and parks, merged with zoning not approved for cultivation
Schools and Parks Buffering
City of Sacramento Zoning

5. Data Preparation Parcel Data Preparation
Zoning data overlaid on parcel data
Select by location used to identify individual parcels
Parcel and Zoning Data Overlay
Parcel Attribute Data
Attribute data added to mark parcels inside and outside legal zoning requirements
Parcels Identified by Legal Status

6. Map Creation Process In Three Steps:
Upload Individual Feature Classes to Service Layers
in ESRI Online
Thematic Map Creation and Symbolization
Web Application Creation and Widget Assignment
and Configuration

7. Service Upload and Map Creation
Individual Feature Classes Uploaded as Services to the ESRI Cloud
Feature Classes Uploaded to ESRI GIS Online using ArcMap Sharing Application
Map Creation
Once layers were created, a new map was created and individual layers were added to the map
Layering order was defined to ensure layer visibility (Points on top of polygons for example)
Visibility limits were assigned to allow layers to appear as defined by zoom level
Symbolization was defined by attributes for each layer to show status
Popups were configured to show appropriate titles and column visibility was defined to show
only data related to theme

8. Feature Popups
When a feature is clicked on, a popup window appears containing data
related to that feature. Attribute columns not incidental to the map
subject were blocked from display.

9. Application Creation
Addition of interactive applications “widgets” requires creation of a web
application.
Widgets are used to add search functions such as routing, address lookup,
or queries.
For this project, three additional widgets were added, “About”, “Search”,
and “Base Map”.
The About widget was created to add a brief description of the purpose of
the map, and how to add data in the Search function.
The Search widget is configured to look up specific APN’s located in the Parcel
layer attribute table, and street address locations in the Sacramento area.
The Base Map widget allows the user to choose between topo, street, and
imagery backgrounds.

10. Performance
Performance on a desktop computer was acceptable, all layers would
draw within a few seconds.
Performance was also tested on an iPhone 6, both connected to a home
wireless system, and on a cellular data connection. Redraw speed was
Definitely faster on wireless, but lag on cellular was only a few seconds
slower.

11. Summary Data Preparation takes the longest time in this process.
The widgets available from the ESRI default selections are very basic
in nature, more complex analysis appears to require designing your
applications.
Allow for base maps to be added as layers!
Improve availability of the application.
