geospatialRUCSBAtlas

A repo that uses local UCSB examples applied to all of the steps of the Carpentries' Intro to Raster and Vector Data workshop.

Scripts run parallel to the episodes (ep_1.r ep_2.r ...) and create maps 'suitable for publication'. (map1.r, map2.r) as laid out in Maps 1 thru 7 below.

The goal is to produce several nice atlas pages of campus that use all the techniques covered in the Intro to GeoSpatial R Carpentry lesson. (Maybe not the NDVI over time, since we've never ever done that episode.)

We have created a Data Dictionary to help us keep track of names.

Getting Started

1: The repo is set up with a source_data folder

source_data is . git ignored, so it's probably not going to get made automatically.

2: Run data_prep.r The goal is for this script to download raw data (into a downloaded_data directory), unzips, and preps any data that's required for the rAtlas. Its outputs go into source_data

3: now each episode and map should run nicely, opening input data from the source_data directory. Any data that an episode writes should be placed in output_data

The narrative of the lesson produces a number of maps, but not particularly well formatted. We'll have 7 well-formatted maps that exist as a shadow to the lesson narrative.

All have a 3 tall x 4 wide aspect ratio, except where noted

Map 1. A wide view of campus with

(issue #7)

• Extent should be the same as #3 inset of map 7.
• NCOS – for now the new lagoon habitat shapefile
• Water
• Bathymentry and elevation in one layer
  • hillshade
• walkways – using bike paths for now
• buildings – for context
• vernal pools:
  • vector data to be create via analysis from DEMs
  • this will come later

Something like this:

Map 2 A stylized thematic map with trees, water, and bikeways

(Issue #8) Trees from ArcGIS Online: Water: NCOS upper lagoon shapefile of bathymetric topo lines or polygons is it this bird habitat file? – yes bird habitats

Map 3 An atlas page layout with 4 insets:

map 4 California Overview

Vertical 3x4 Western US

map 5 The Bite of California

Vertical 3x4 Needs to be further zoomed in.

map 6 Extended Campus

(issue #14) Landscape 4x3 * extended campus will have maptiles background? * Bacara-ish to 254/101

Maps 4-5-6:

7 Campus Detail

Wide Landscape * A stripped down version of #1

Map 3 sketch:

8 RS Imagery

Include a Planet feed. (Issue #15) For starters, this will be several pre-fetched campus images. 4- and 8- bands!

9 Analysis: Find landscape depressions on Campus DEM

ie: identify vernal pools

10 Analysis: Find bike paths that cross water?
