2015-07-10: How to view Oblique Imagery (In a Viewer)

As of August 2015 we are offering two ways to access oblique imagery (Pictometry).

  1. Using a login (staff can contact us for an account) at pol.pictometry.com.      (Please note:  If you formerly used a login account and still need the additional features, such as markup tools and saving a project, contact us to set this up for you.)
  2. Within our Geocortex HTML5 Viewers (Planning or Road Viewer, etc). Read below for details on this option.

2015-05-08: EZ Search has Changed!

EZ Search Has Changed!

We have been working hard for the past few months to bring you a new EZ Search site that will better serve your needs.

All the same information is available, along with some new features:

  • Mobile Friendly – No matter which device or browser you use to view our site, it will look good.  Even tablets and mobile phones!
  • Redesigned Interface – The site is cleaner and easier to navigate than before.
  • More Informative Reports – When you search by Owner or TaxMapID, you’ll get as much information as possible for that parcel.
  • Better Auto-Complete – Start getting suggestions from the first letter you type for most input boxes.
  • Improved Results Table – Once you get your search results, you can filter the results even further to get to the information you want even easier.
  • Redesigned Report – The reports now feature more information, a map, Google® Street View, and a new layout that groups information in a way that you can find the information you want even faster.
  • Share Easier – You can send someone the link to the search or report you are looking at, and they will be able to see the same information.
  • Explore Other Sites – There is a section for our other GIS Sites right at the top.  So, now, finding other applications or downloading data is even easier to get to.

(We have some additional updates planned in May/June/July 2015 for our viewers.)

2014-06-04: Updated 2014 Imagery Now Available

We are excited to announce the availability of 2014 imagery in our viewers. This includes both aerial and oblique imagery from Pictometry. Please reference this previous post to learn how to access oblique imagery.

Most urban areas have 3” resolution while rural areas have 9” (check out this link to observe how resolution makes a difference). For comparison, our 2009 ortho-imagery resolution was a mix of 6” and 12”.

ArcGIS Desktop users within the county are making use of a mosaic dataset for 2014 aerials. There is a layer file for quick access S:\layers_yorkcounty\Orthophotography available for staff.

Dispatchers are referencing both Pictometry obliques and aerials for police, fire and medical (911) calls within the New World CAD software.

There is another imagery acquisition scheduled for 2016 that will include obliques and aerials (at 9” only).

2013-11-05: State of the County GIS Program – Existing Patterns of Use & Road Ahead

This message is intended as a very high level overview of current GIS solutions deployed and a preview of future efforts.

York County offers the GIS Online services to both citizens and staff as a window into the information county staff maintain for daily operations.  The GIS team takes pride in making efforts to ensure the information in our GIS Online can be used to make timely, informed and accurate decisions.  

The online web mapping solution we offer will continue to undergo upgrades as technology around us improves.  We foresee limited impact upon you, as a user, in the future as the majority of change will take place “behind the scenes.”  

The biggest advancement we are excited to announce is the ability for the growing mobile workforce to use our information products on mobile devices (phones and tablets, iOS, Android, or Windows).  Mobile access is already available and we promote this through our website.  In 2014, we will have even more in our web options.  If you would like an early look, browse to the penniesforprogress.net interactive map.

Now that development has returned to York County, there is a demand and need for refreshing our imagery.  The last imagery was acquired in 2009 – we are excited to announce that we will have both oblique and aerial imagery available in 2014 with additional plans established for 2016.

Users of our GIS Online services can access both oblique (Pictometry) and aerial imagery through our EZ site.  The oblique image can be launched in a viewer with parcels layer or in a viewer synced with the map.  For more information on this, see our blog posting describing the options available.  

It has been said in local government, there are only two kinds of data, spatial and financial.  Even those two come together!  Within the last couple years there has been another exciting addition in the use of Cityworks, a GIS-Centric asset management software.  In four departments, staff have begun using this daily to become better stewards of County infrastructure assets and more responsive to citizen inquiries.  We are exploring citizen engagement opportunities to promote communication among staff and with the public.

Also, don’t forget GIS Day this November 20!  Each year, this day is an opportunity to demonstrate how we use GIS in our daily work and how this powerful technology plays a role in making our world a better place!  This year the GIS Team plans to gather and share the results of the recent GIS HealthCheck, an assessment of the business utilization of the GIS, and ways to get the most out of our GIS.  While our event will be for staff this year, please do consider attending the event in Charlotte, which is well established and has been held since 1999.

2013-09-13: Introducing Map Themes

There are a variety of users with many different needs who make use of our viewers.

We recently begain using Layer Themes to help you access information needed for certain uses within the same viewer.

We encourage users to use the “EZ Site” to search for and access basic property information. If an interactive viewer is needed to ask specific questions, consider using one of the “Application Links” (highlighted in red below) to launch the viewer with layers available and visible.


Please keep in mind that you always have the option to interact with ‘All Available Layers’ if needed (see screenshot). Once a viewer is launched and you need to view other layers, just use the drop down and make the change (no need to return to EZ site.)

For example, to review sales comps on the map,

a. launch the Dynamic GIS map “Parcel” link


b. use the ‘Parcel Property’ map theme within the Planning Viewer.

In the map layers list, look for the ‘Yearly Sales’ layer as in the screenshot below.

2013-08-12: Got Coordinates? Need Coordinates?

There are various uses for using an X and Y coordinate pair when using a mapping system such as our EZ site and related viewers, however most of us will geocode a location with an address (see screenshot below for 6 S Congress St from our EZ Site).

Within the EZ Site we offer each address or parcel (label point) as X and Y coordinate pairs in the various coordinate systemsLat/Long, as USNG and as SC State Plane.

Here are the suggested tools for a few use cases:

  • What do you do if you want more specific point information through interacting with a map (Plot Coords)?
  • What if someone supplies you with Lat/Long coordinates and you need to plot those on the map (Enter Coords)?
  • Did someone give you a spreadsheet with Latitude in one column and Longitude in another, a long series of locations to plot at one time (Add CSV file)?

Don’t fret, the screenshots below describe the tools that allow you to accomplish just this.

EZ Site – Address and Parcel Report Page: Geographic Information

The Analysis Tab

The following graphic explains how to use the coordinate buttons and settings.

A graphic will appear on the map where you click or corresponding to an entered value.

On the Maps & Data Sources tab, use the ‘Add CSV file’ button to plot a series of locations on the map at one time. The CSV file should have this two column format: Latitude, Longitude

Note that what you added will display in the Map Layers list as a ‘graphics layer’ with the same name as your CSV. You can then symbolize the layer and make a printable map.

Opens a navigation window so that you can find and add a comma-delimited spreadsheet (CSV) with data to the map.
