Cost to Lay Cable for Caribou Residents

February 3, 2012 Leave a comment

Of the 320 buildings not serviced by Time Warner cable how much would each resident/owner of the buildings have to pay to get cable?  Assuming each building is owned by separate resident and assuming each resident approached Time Warner individually (not as a collective group)  they would be expected to pay an average of $2,590.  $828,600 / 320 = $2,589.375.  However, some of the residents are within a half a mile of where the cable terminates and others are several miles.  Between $1,000 to $60,000 per installation.  Below is a graph chart that shows how many residents would be expected to pay based on cost.

Based on a median income of $36,779 as of 2009 for Caribou residents I belive the cost is out of most people’s reach, even if Time warner contributes $1,000 per installation as they did on the estimate they gave me.


Rural Internet in Caribou ME

Been a while eh?  A while back (June of 2011) I mapped out who could get Time Warner service in Caribou ME and who couldn’t.  I used the 2010 NAIP imagery to digitize all the homes in Caribou.  The homes in the rural areas I verified that they appeared to be used as well as the location where the cable seemed to terminate on the telephone lines.  Furthermore those homes/buildings that were set further back than 300 feet were also excluded since according to Time Warner this is too far to install cable for free.  These findings were compared with the results from to make sure I wasn’t excluding or adding any homes that did/did not have cable.  Based on this methodology Caribou had 3200 building of which 320 did not have access to cable.

By measuring where the cable stopped and which buildings did not have cable I estimated that for the whole city to be serviced an additional 218,726 feet, or 41.43 miles of cable would need to be laid.  At a cost of $20,000 per mile this would equate into a cost of $828,600 for Time Warner.

3D Maps in Dungeons and Dragons Online

September 10, 2010 3 comments

I grew up on Dungeons and Dragons and have loved the imaginary landscapes. Recently I have been playing Dungeons and Dragons Online with my kids. Turbine has created gorgeous and well thought out dungeons but their map system is 2D which makes it difficult to navigate unless you have run the quest multiple times.  I’ve worked on some of the maps to try to make them more understandable with limited success.

To overcome the limitations of a 2D map I have played around with creating a 3D map.  By plotting known locations within the game I can export these quasi X,Y locations into ArcGIS 9.3 along with a 2D picture of the dungeon and plot the layout.  Then by exporting a DWG file into Google Sketchup I can create a 3D environment and add other 3D models to the dungeon.

Using this process I went from a 2D map to a 3D map.  There are quite a few things I can do to improve my results but this is one of my first forays into 3D mapping.

ESRI UC 2010 MGIS Presentation

July 31, 2010 Leave a comment

The ESRI UC 2010 was not as exciting as I remember when I first went there in 2005.  There were a few good discussions but overall it all seemed rather redundant.  However, there were a few notable exceptions. I also presented my Penn State Masters of GIS presentation. So now I have to make a few fixes to the paper and I’m done. I uploaded my presentation as unlisted, just follow the links below if you want to watch. 😀 Yahh!!

ESRI UC Almost Here

June 24, 2010 Leave a comment

Finished up my Masters of GIS project and submitted the paper to ESRI and now working on the Power Point for the conference.  I will be presenting at the ESRI UC on Jul 15 from 3:15 PM to 4:30 PM in Room 29 D, in the Terrain Modeling and Analysis paper session.  My presentation is called, Viewshed Creation: From Digital Terrain Model to Digital Surface Model. 

I will be glad when this is all over. When the papers become available through ESRI I’ll post a link and when my Power Point is done I’ll share it here also.

Viewshed Creation: From Digital Terrain Model to Digital Surface Model

February 2, 2010 Leave a comment

I recently presented to my faculty on my proposed Masters project.  My school does not have a do a thesis (thank goodness) instead we do a project and present at a conference.  Below is my proposed project given to my peers, faculty and my advisor.

Endangered Runaways

February 16, 2009 1 comment

On Sunday night I watched a few news stories on MSNBC concerning sexual slavery and prostitution, including “Sex Slaves in the Suburbs.”  The premise of this show was that young females are being kidnapped and forced into prostitution against their will.  Additionally, law enforcement treats the kidnappings as runaways.  The show was quite moving with a particularly emotional testimony by a young female.

I was curious how prevalent cases of runaways were in the United States.  I went to the National Center for Missing & Exploited Children (NCMEC) website and performed a search for all “Endangered Runaways” in the US that occurred between 1/1/2008 and 2/9/2009.  I found 621 individuals, both male and female.  The Department of Justice (DOJ) defines an endangered runaway as a runaway that has certain “factors such as substance dependency, use of hard drugs, sexual or physical abuse, presence in a place where criminal activity was occurring, or extremely young age (13 years old or younger).”

Endangered Runaways 01/01/2008 - 02/09/2009

One of the only studies I found concerning runaways was the DOJ study, Runaway/Thrownaway Children: National Estimates and Characteristics.  According to the report there were quite a few more endangered runaways back in 1999 that my findings at NCMEC’s website seem suspect.  The report states that there is “suggestive evidence” that the incidences of runaways have  declined in recent years.  But it seems my findings are quite low compared to the number of expected endangered runaways based on the report.  I am not sure the discrepancy, however it is probable that some of the endangered children in the DOJ report were recovered but still reported which is in contrast to the NCMEC which only lists currently missing endangered runaways.  Also there is the possibility that  the NCMEC and various state agencies have not identified the children as endangered, simply runaways.
