R Open Labs – Basic Syntax

Hi all, last Wednesday we kicked off the first session of R Open Lab in the DSSC( based in Lehman Library). We started with basic syntax and briefly discussed how to explore the features of our datasets. We used data from Wal-Mart and we will continue exploring this dataset for the next few sessions. Beginners are welcome to join!

Using R with ArcGIS

With a successful collaboration between DSSC and ESRI, a hands-on workshop on ESRI R plugin was presented by Shaun Walbridge, a senior developer from ESRI, on Wednesday, April 20. Shaun provided an in-depth tutorial on how to use R in ESRI, and answered questions from students and librarians.

Our audiences were from a broad background: librarians from Columbia and other institutions in NYC, PhD students, Master’s students, people from administrations, etc.

Presentation Highlights:

SP data types in R
  • 0D: SpatialPoints
  • 1D: SpatialLines
  • 2D: SpatialPolygons
  • 3D: Solid
  • 4D: Space-time
R — ArcGIS Bridge
  • Store your data in ArcGIS, access it quickly in R, return R objects back to ArcGIS native data types (e.g. geodatabase feature classes).
  • Knows how to convert spatial data to sp objects.
  • Package Documentation
  • Upcoming: Conda for managing R environments

R Open Labs: mi

Last week, Professor Ben Goodrich stopped by R Open Labs to show us how to use the mi package, which he worked on with Professor Andrew Gelman.

As the name ‘mi’ suggests, this package does multiple imputations to help you predict missing values in your data sets.

Check out the demo if you’d like to give the mi package a try!

R Open Labs continues every Weds, 10 am -12pm, through April 20th.  Drop in anytime! 

 

 

Intro to GIS workshop, Friday 9/27

Registration is now open for the first of two Intro to GIS workshops. The first will be held next week Friday 9/27 between 11am – 1pm in the DSSC Data Service, Lehman Library room 215.

We will offer it again on Friday 10/4 at the same time.

The workshop will give a basic overview of GIS, data models, spatial analysis, projections, finding data, and working with your own data. There are two hands-on exercises, both using ESRI ArcGIS software so everyone who attends will get a chance to use the software and explore some of what we cover in the talk.

The Intro workshop is meant for anyone who either has had no previous experience with GIS or for anyone needing a refresher.

Introduction to Cartographic Design 12/2

Next Friday 12/2 between 10:30am- 12:30pm, EDS will offer the Introduction to Cartographic Design a workshop led by Eric Glass GIS/Metadata Librarian.   This workshop is geared towards students taking introductory GIS courses who are in the process of producing project presentations and papers as the end of the semester approaches.  The two hour workshop will give an overview of some major cartographic concepts, including:

–        Communicating your message effectively
–        Creating clear, balanced layouts
–        Symbolization
–        Labeling
–        Use of color
–        Map elements

Registration is not limited to current students in GIS courses.  However, there is an expectation that attendees have had some level of exposure to GIS software, specifically the basics of working within the layout view in ArcMap as there will be a hands-on component working with ArcMap.

Registration is on the DSSC workshops page

Digitizing, georeferencing, and creating new spatial layers workshop 11/11

 

This Friday 11/11 Eric Glass will lead a workshop on digitizing, georeferencing, and creating new spatial layers. 

He’ll give an introduction to techniques for creating new spatial layers from various sources, particularly georeferencing and digitizing from paper and imagery.

This will be a very practical, ArcGIS-centric workshop and will consist of a short lecture followed by individual hands-on exercises using ArcMap in the Data Service lab (215 Lehman Library).

An introductory level knowledge of ArcMap is required to attend.

Register for the workshop.

GIS Workshop – Coordinate Systems & Projections

Next Friday 10/7 from 10:30-12:00 there will be a new GIS workshop "Coordinate Systems & Projections" offered in EDS. This workshop will provide a very generalized introduction to the components of Earth coordinate reference systems and map projections. The focus will be on providing the basic concepts needed for working in GIS applications, specifically ArcMap.

workshop schedule update

3DMap Building ExampleWe’ve added a Intro to GIS workshop in place of ArcPy I on 7/20 since we’ve received several requests.

Intro to ArcPy will happen the following week on 7/27, we’ve decided to have a single workshop instead of two.

Registration opens one week prior, the full schedule can be found on the DSSC Workshops page.
