Lab 10 geog 353

This is our final Course evaluation and it is a take home final exam so i will not be putting it up here but over the course of this project i have learned a lot about different methods and types of arcgis maps and i feel that using them in animation is a realy good too to pic k out trends and such in the academic community and more animated maps should be used

here is my webpage URL so you can check them out. They are under Geog 353 animations page. Link is on the bottom of my webpage.

 

Lab 9 geog 353

So the  first GIF animator I used was ImgFlip and it worked okay but the image quality was pretty bad. The maps were really grainy and fuzzy.  I had control over its delay, width, height, and quality.  I do not think I will use this GIF animator for my project.

GIFMaker was the next GIF animator I tried and I liked it a lot better and I could control Canvas size, speed, and repetition. This GIF animator is on the short list for my project animations. The animations are a little fuzzy.

Make a GIF is next. This site is like GIF maker and it is pretty good. You can control speed and size of your animation. This makes the short list and also plays your animation in a loop.  The animations are a little fuzzy.

The fourth site is GIFCreator and i like this one it is simple and fast.  You can control size and speed.  It plays you animation in a loop as well. This site when the animation is downsized makes your maps a little fuzzy around the lines and boxes.

I used GigCreator to create my animated maps that will appear on my webpage.

Different types of files used in acr2earth

.dbf__ is a simple font file

.prj__ stands for ProJect and is a simple data storing file. it can store settings and such

.sbn__ binary spatial index file used only by ESRI software

.sbx __ an Adobe file created by ESRI

.shp__ is a shape file

.shp.xml__ a more complex shape file that was exported?

  .shx__  complies shape entities

 

 

Lab 7 geog 353

For my choropleth map I was looking to split my data at zero with two below and three groups above but i thought that was going to be hard to show the relative significance of the population change so i ended up bridging zero by 10% on each side since a 10% increase or decrease is around the boundary of have a large impact on the county level.  This way it only shows significant gains and losses. Losses were one color and class gains I have 2 or 3 colors and classes.  I use a gradual color increase of tans to red in the gains and the green as a loss.

Color uses for all of my maps is in the tan-orange-red color schemes. I think this joins some of the natural colors of my state into the overall aspect of my maps.

graduated symbol maps i used five classes and sizes of house since i  thought that was a good symbol to use with population change i also changed the color between classes between two colors to help follow the changes.

proportional symbol maps. I just used a circle since i already used a house and a circle is a good way to show proportions. Also its red

dot density maps  I used a tan background with orange red dots at a vaue of 1000 since i thought the showed to population in a good way since i have areas of low population and high population.

Lab 5 geog 353

I used the NAD 1983 Coordinate system because when i was clicking on all the different system choices this one looked to me to square up my state in the window in ARCGIS.
My dbf. file was checked and I moved forward to linking my dbf file to the county fips codes in arcgis

Lab log 8 geog 353

In this lab we exported our choropleth, graduated symbol, proportional symbol, and dot density maps from Arc GIS in the form of .gif files so that we can animate them in our lab 9 and them put them up on our web page as animations. The maps are from 1900-2013 so it will be interesting to see trends in the maps.

Geog 353 lab log 4

In this lab I relearned the basics of  ARC GIS.

We made file connections along with pulling specific data layers out of the larger data files.

We looked at attribute tables and saw what kind of data we can create maps off of in the table.  Some of these attributes in a data layer can be pollution (blue) and number of house holds ( orange) in each census block in the census block data layer.

The red and blue lines you see on both of these maps above are the interstate highway system.  We pulled it out of the roads and highway data layer.  I did so by selecting just the interstate highways and then making the Interstates into there own layer.  I then just applied this new layer to the maps.

Another fun thing we played around with was the type of projection you make can have.  Map projections are a way to represent the 3-D world on a 2-D surface like a map. These projections can make the world map look like stars, cubes, along with other shapes.  I also put the latitude and longitude coordinate system onto the world map.

Some interesting things I explored were the arc toolbox and I looked through the water based tools.  You can do things that deal with surface water along with some ground water equations.  Theses tools are what i found on the wed a long time ago and said would be fun to use but i never found them in our Arc GIS program till now.

Some terms form the lab that we are to define:

Map Document (.mxd files)– they are just files used by arc gis to save the changes you have made to the data layer with out changing the data layer itself.  They are just files that save the modifications to the data layer and can not be opened outside of arc gis.

Table of Contents– It is where your data layers are and you can turn the data layers and data frames on and off to show different aspects of your map.

Data Frame—- a data frame holds different map/data layers in the table of contents and can be turned on and off. Only one data frame can be active at a time.

Map Layer— a map layer is a single component of a map and together map layers map out the different aspects of your maps.

Attribute table— an attribute table is with in the map layer and holds in a tabular form all the data in that specific map layer.  It can be numerical data like populations or type data like names.

lab log 3

Converting the data into an excel file was interesting and learning to change the file type when you save it was interesting as well.  you can move a common excel file to open office then you can create a DBF file which ARCGIS likes the best.  BUT you have to be careful and not screw up your data and you have to make sure you have the data in the excel file just right before you convert the file.  the file once made cant be open because it will get messed up. you can only use it in ARCGIS because that is what it likes and wont mess the file up.

The FIPS codes are interesting and they seem to be a great way to log counties in the computer world.  The only problem that i can see is what iff you have to add two counties that are already in between two current  ones.  You might just have to change some numbers or change the name of the new County.
