Impact of Google Maps API v2 shutdown on Openlayers base layers and a easy solution

Be The First To Comment
Finally on Nov 19 2013, Google shut down Google Maps v2 API, which was depreciated in May 19 2010 but was working continuously Nov 19. I was aware of version depreciation, but I procrastinate to upgrade till last minute because of working on too many other things. While checking my Web map (built on Openlayers, Geoserver and Google Maps as base layers (Google Maps API v2) on Nov 20, I saw two map controls one from Openlayers and other from Google Maps API also noticed that map application was unresponsive.


Looking around I found easy steps to fix it without major change in the code-

New 2014 GIS Internship/Jobs Opportunities

Be The First To Comment
1) 2014 Summer Opportunities: Yosemite National Park, CA
These four summer positions involve a complete remeasurement of the 25.6 ha Yosemite Forest Dynamics Plot, located near Crane Flat in old-growth sugar pine/white fir forest. The plot burned at generally low to moderate severity in the 2013 Rim Fire. Tasks include revisiting each tree and snag; recording mortalities, ingrowth, and newly fallen wood; measuring scorch and snag heights; and mapping shrub patches, down CWD and areas of the forest floor that did not burn. Other tasks include measuring fuel consumption along fixed transects, installing and measuring dendrometers, and collecting data from associated instrumentation. Mortality checks require hatchet use. Staff will supervise students and volunteers.
Qualifications: Previous experience taking vegetation research data, working safely in challenging environments, and following complex data collection protocols is required. Candidates should demonstrate the ability to solve problems and to work both independently and in teams of two or three. Work will involve moving through sometimes steep, rocky terrain with delicate and expensive equipment, as well as the ability to carry up to 15 kg of additional gear. Work experience in post-fire forests strongly desired, as is some knowledge of western flora, tree pathogens, and forest insects. Staff must have a driver’s license and a Wilderness First Aid/CPR certification (or higher) valid until August 31, 2014 (if you are not certified, please include your plans for certification in your cover letter). Other: Practical experience in the operation and maintenance of computer, electronic, and mechanical equipment; familiarity with a variety of software and instrumentation; and experience with periods of outdoor living are all positives.

MAGIC GIS 2014 Symposium

Be The First To Comment
The Mid-America GIS Symposium, MAGIC 2014, is quickly approaching and will be held April 27 to May 1 at the Westin Crown Center April 27 - May 1, 2014 in Kansas City, Missouri.

GIS covers such a broad range of subjects, applications and types of people that use it, that developing a conference program that meets everyone's needs is a challenging task. Even more challenging is an attendee trying to figure out exactly which sessions or topics will be most interesting and helpful. MAGIC 2014 is intended to focus the content of the presentation options into a program specifically geared to each attendee's needs.

Your 2014 Program Committee is working very hard to bring you the best Symposium yet. If you have ideas or comments, please send them to the Symposium Chair.

Anyone is free to submit an abstract to MAGIC 2014.
Submissions should be received by December 6, 2013.
You will be notified by January 20, 2014 if your presentation was accepted.

US address correction, address verification, and geocoding using ZP4, Google Geocoding API, and Bing Maps API

5 Comments

From a couple of months, I have been involved in Tax certificate address verification project for educational purpose; I have around 8 million parcel address  collected and maintained by different tax collecting agencies in various format for instance COBOL ,CSV, ASCII, Excel , and some are even in pdf for their tax districts. 

My task was to find the address from those different files and export them in CSV with corrected standard USPS address format (STREET, CITY, STATE, and ZIP) to make Universal Tax File format for data analysis by removing unwanted data from the address rows.  Initially, I used ZP4 software, it has “official United States Postal Service data files on a single DVD-ROM that provides a powerful tool for automatically determining the correct mailing address, ZIP + 4 code, and mail carrier route number for any location in the United States”, works fine for few address (about 15%) which has proper USPS standard address format. The real challenge starts with remaining   85% of the parcel address that has no USPS standard address format (either address without city and zip information or the vacant parcel lots that cannot accept mails and therefore not entered in the USPS mailing address database).

Looking around the Web, Google leaves me with tons of pages entitled on address correction and validation including close source and open source software APIs, tools, and datasets, but hard to figure out which method works for my project in terms of address quality(address was poorly written), quantity(8 million addresses), and resources (cheap and easy to implement) . After spending few days here and there, finally I come up with a solution that works for me, an integrated address correction strategy using ZP4, Google Geocoding API, and Bing Maps API.

Here, I am going to share how ZP4, Google and Bing integration makes my job easy and relatively cheap to validate and correct US physical street addresses.

How to Land on Top-Paying GIS Jobs

Be The First To Comment
Author Bryan Frost, published a 88 page book on “How to Land a Top-Paying GIS mapping technicians Job”, which compiles all the information candidates need to apply for their first GIS mapping technicians job, or to apply for a better job for instance guide to opportunities, resumes and cover letters, interviews, salaries, promotions, what to expect from recruiters and more.

The amazon.com describes the book as-
For the first time, a book exists that compiles all the information candidates need to apply for their first GIS mapping technician’s job, or to apply for a better job.
What you'll find especially helpful are the worksheets. It is so much easier to write about a work experience using these outlines. It ensures that the narrative will follow a logical structure and reminds you not to leave out the most important points. With this book, you'll be able to revise your application into a much stronger document, be much better prepared and a step ahead for the next opportunity.
The book comes filled with useful cheat sheets. It helps you get your career organized in a tidy, presentable fashion. It also will inspire you to produce some attention-grabbing cover letters that convey your skills persuasively and attractively in your application packets.
After studying it, too, you'll be prepared for interviews, or you will be after you conducted the practice sessions where someone sits and asks you potential questions. It makes you think on your feet!
This book makes a world of difference in helping you stay away from vague and long-winded answers and you will be finally able to connect with prospective employers, including the one that will actually hire you.
This book successfully challenges conventional job search wisdom and doesn't load you with useful but obvious suggestions ('don't forget to wear a nice suit to your interview,' for example). Instead, it deliberately challenges conventional job search wisdom, and in so doing, offers radical but inspired suggestions for success.
Think that 'companies approach hiring with common sense, logic, and good business acumen and consistency? ‘Think that 'the most qualified candidate gets the job? ‘Think again! Time and again it is proven that finding a job is a highly subjective business filled with innumerable variables. The triumphant jobseeker is the one who not only recognizes

How to get raster pixel values along the overlaying line?

Be The First To Comment
One afternoon at Java City, my friend Eric and I were discussing about the ways to to get raster pixel values along the overlaying line. The conversation encourages me to write an quick and dirty solution to solve the issue. The following R code snippet helps to conceive an idea to extract the raster values which are intersect or touch by the overlaying straight line in easy fashion using R raster package.

#Print the raster pixel values along the overlaying line in R. The line's start and end row/col (coordinates) must be provided.

library(raster)
#Create an arbitrary raster, for instance I used a names of color as raster pixel values.
r <- as.raster(matrix(colors()[1:100], ncol = 10))

#Start coordinate of a sample line
x0=1      #row = 1
y0=3      #column = 3

r[x0,y0]

#End coordinate of a sample line
x1=10        #row =10
y1=7 #column=7


#Easy sample line generation algorithm : A naïve line-drawing algorithm

dx=x1-x0
dy=y1-y0

for( x in x0:x1)
{
y = y0 + (dy) * (x - x0)/(dx)

#Print the raster pixel values along the line
print(r[x,y])

}

Pretty simple concept. You can tweak the code & the line drawing algorithm as your requirement. There are several line drawing algorithm available in the internet. Here I used a simplest one that I found.

First Image of Earth from LandSat 8

Be The First To Comment
The LDCM/LandSat 8, which is launched from Vandenberg Air Force Base on February 11, 2013 is started   to send Earth’s picture to the ground from the space. This week, the Landsat Data Continuity Mission (LDCM) released its first images of Earth, collected at 1:40 p.m. EDT on March 18.LDCM is performing as planned and everything is on track for a May operational transition. LDCM is a joint mission of NASA and the Department of Interior's U.S. Geological Survey.

According to NASA website, LDCM’s first instrument, Operational Land Imager, or OLI instrument, that took the natural color image. The natural color image showed the landscape in the colors our eyes would see, but Landsat sensors also have the ability to see wavelengths of light that our eyes cannot see. LDCM sees eleven bands within the electromagnetic spectrum, the range of wavelengths of light. OLI collects light reflected from Earth's surface in nine of these bands. Wavelengths on the shorter side include the visible blue, green, and red bands. Wavelengths on the longer side include the near infrared and shortwave infrared. LDCM's second instrument, the Thermal InfraredSensor (TIRS) detects light emitted from the surface in two even longer wavelengths called the thermal infrared. The intensity of the emitted light at the longer wavelengths measured by TIRS is a function of surface temperature.

Good Book for GIS Beginners : Book II

Be The First To Comment


Understanding GIS: An ArcGIS Project Workbook, is a very user-friendly written book for those interested to begin using ESRI ArcGIS Desktop 10 or ArcGIS Desktop 10.1 using real data from the City of Los Angeles' Department of Public Works, Bureau of Engineering's Mapping Division, and Department of Recreation and Parks and to manipulate it using the power of GIS.

 Don't expect to become a GIS expert at the end because this is simply a good introduction to ArcGIS. The book guides the reader step-by-step, mouse-click-by mouse-click, decision-by-decision through a GIS project to determine for yourself which locations along the river are best suited for public recreational use in Los Angeles. At the end, you will have learned many of the fundamentals of GIS generally and ArcGIS specifically which aims at finding a suitable land parcel(s)for a new park area in Los Angeles .You use real data which comes in the companion DVD. When you reach the final stage in chapter 6 and follow all the careful steps to manually select the best areas and you learned why you do so, you discover in the following chapter (chapter 7) that you can do the same in a much quicker way by using a visual graphing tool, a marvel in my opinion of ArcGIS Desktop.

Python Scripting for ArcGIS

Be The First To Comment

Python Scripting for ArcGIS is a new text from Esri Press by Paul A. Zandbergen (2013). It isn’t the first Python book for the geospatial community or even focused on ArcGIS, but it is the first that has the Esri logo on it. Much like other recent books on Geo/Python we have seen, it focuses on integrating an introduction to Python with the industry specific materials. As Frank mentioned when he highlighted the book in a previous podcast, this allows users to gain exposure to Python, but it doesn’t fall back on the (in my opinion) bad habit of most programming texts of spending half of the book on the language and concepts before even getting to the application in the specific area. There is a time and place for that approach in Python specific books. When you add another software library to a book, then use it from the get go.
