Lab 4-Digitizing, Editing, and Sharing

Introduction

The forest service want to create a new campground in northern Utah on the east side of the Wasatch Range, and north of Liberty. For this lab I am going to design a campground plan by making a map and GIS files for an internal review committee over the web. I will use vector data to design the campground. I will practice editing skill by manipulating, modifying, drawing, and digitizing the vector data. 

Lab Objectives

  • Edit existing vector data layers
  • Create new vector data layers and edit them 
  • Edit and create tabular data
  • Share vector and tabular data with other GIS users

Lab Tasks

Task 1: Create Campground Design Map

Step 1: Set up map projection and locate lake

I first downloaded and extracted the Weber County roads file from lab 4 on Joe Wheaton's webpage. I used the go to XY tool to find the location of the campground from the coordinates that were provided on the lab. The site is located next to a lake. I then edited the roads layer and created a feature class and sketched a line to represent a road for access to the campground.

Step 2: Create Two New Feature Classes-Point and Polygon

I created two more layer files, one for campground and another for campsites. I did this by going into the catalgue, navigating down to where I want to save my files. I right clicked on the folder>new>shapefile. I specified the campground to be a line file and the campsites a point file. I set both of their projections to NAD 1983 UTM zone 12N. The files were added to my table of contents.

Step 3: Digitizing campground, campsites, extended roads

When I reached this step, I realized I wasn't happy with my campsite location, I wanted to change it to the other side of the lake, because there is more vegetation. I went into an editing session and snipped out part of my road, and moved it for access on the other side of the lake. I created a polygon around the lake where I want my campground. The area it covers is 1.2749 HA. I then added points to my campsites layers where I wanted the individual sites to be located. I edited the attribute table to number each of the sites, and added some fields to describe the site, like whether or not it is located by the lake, what side of the lake the sites are located, and whether the site has parking. I edited the road to go through my campground, and connected it to each campsite. To download a PDF of  my table click here.


Step 4: Create Formal map with area and road extension length

Task 2: Share GIS Data for Campground Design in Different Formats

Step 1: Sharing Data Files

I created a file cabinet sub-page for this page. I combined all of my map data file, and created layer files to zip and upload onto the page. I zipped and uploaded my map file. I also made a map package in ArcMap and uploaded it here. I created  KMZ files for my interactive map and uploaded them here. I also made and uploaded a file geodatabase. 

Step 2: Google Map

Step 3: Final Images

Step 4: Upload to ArcGIS Online

I created a layer package file by right clicking on a layer in my table of contents and choosing the create a layer package option. I added all the layers I wanted to include, and filled out the remaining fields. I had to make sure that the layer file that I am creating the file on had a description associated with it in the properties. I then created a free account with online ArcGIS and uploaded my layer package onto my content.

Step 5: Descriptions of File Types for Interview Committee

 File TypeName DescriptionPros  Cons Software
 .mxdMap Document file This files gives access to a map documents along with properties and methods.  Gives access to almost all other map document properties Needs ArcGIS to run. ESRI ArcGIS
.mpk Map Package file An easily transferred data packaged that contains a map document and the data for the layers used for the  map.All map data is easily stored and transported.  Needs ArcGIS to run. ESRI ArcGIS
 .shpShapefile  A simple file format that stores vector data. These files store geometric location and spacial information in an attribute table. You can add data, join attributes, and edit data.File is limited to 2 GB. The file needs many extension files to transfer and share data.  ESRI ArcGIS
 .lyrLayer file  A layer file is a dataset that stores geographic attributes, text, and labeling properties. Maps are made up of a series of layers and are layered on top of each other in a certain order for display. Others can access layer files, and it will draw the same.  Layer files derived in a newer version of ArcGIS will not draw on older versions. ESRI ArcGIS
 .kmz Keyhole Markup Language file A file in the XML format used to represent spacial data on google earth or ArcGIS.Allows maps on google earth that can be shared. If KML files are too large they can appear distorted.  Internet Explorer, Google Earth
 .gdbGeodatabase file  A collection of geographic datasets held together in a single file. Files can be shared or private. Has the capacity to store large files. Limits the use of a single file geodatabase with multiple users. ESRI ArcGIS
 .lpkLayer Package file  A single file package of compressed layers with reference data sources. Easy access to all of a maps layers with little storage space. These packages are no alw ayscompatible with older ArcGIS versions, like 9.3.1. ESRI ArcGIS

Summary

I enjoyed making this campground map. My goal was to be able to display everything on one map without making it look too cluttered. This lab has shown me that are  multiple ways of sharing and displaying data depending on what  your end goal is. Dealing with ArcGIS tools and glitches will help me share data quicker in the future.
