Lab module 1 process was daunting and at times frustrating for this first timer.  Data had to be extracted from the R: drive to my S: drive.  4043 GIS Intro folder.  Module 1 folder.  Except the first go at this I misspelled Module as "moduel".  When I corrected the spelling then I lost my data.  So back to extract again.  The outline in the overview provided for this lab worked very well.  It was slow going for me as this is all so new.  Map document (.mxd) does not contain data.  To move or share MXD file the data files must go as well.  To share the map export it to jpeg (hoping this eliminates the need for data files).  I explored the toolbar: zoom in and out, taking notice of the scale display changes 1:1000 being bigger than 1:1000000, similar to fractions 1/1000 is bigger than 1/10000000).  I panned all around while zoomed in and lost myself, but was able to center by right clicking World Countries layer and selecting zoom to layer.  I looked at metadata in the .xml file.  Looking was all I am able to attest to, didn't understand most of it (another opportunity to learn latter). I sorted an attribute table by a field (column) and was able to locate items on my map by locating the record (row) right clicking the farthest left cell and clicking zoom to. I selected islands on the map utilizing the select features tool and obtained information about the islands by show selected records button.  I identified parts of my map by utilizing the identify tool. I located areas of my map by using the find tool and then right click the result I need to pan to the location.  I used the xy tool to locate on my map and used the measuring tool.  Although since the polygon to be measured was irregular shaped I am not sure how there would be a correct answer for a measurement (there would be different answers based on the location of the measurement). 

The map itself:  The world Countries with a layer for cities.  I changed the symbol for the cities. The color of the countries is graduated by population.  Changed the view from data view to layout view and utilized the layout toolbar.  The layout toolbar for use in layout view (the data extent does not change) and the tools toolbar is used for navigating the map view.  Changing the data frame from portrait to landscape by select and drag the top right corner of the data frame posed some clumsy ineffective attempts for me.  I was able to right click inside the data frame, click distribute and fit to margins to get it (much easier). I added essential map elements: North arrow, scale bar, title, legend, data source, my name (and later the date of creation).  Finally exporting the map as a jpeg. and saving it.

Using ArcGIS Help in my browser was a no go for me.  I could pull the web site, and would search, being sure it was for my version 10.5.1, and the result was no results available try again later.  So I improvised and used wiki.gis.com and then moved on to the ArcGIS desktop help.

Overall this was a ton of new information.  Hopefully I will have less technical issues and be able to move a little quicker next time.
