boydsmaps site info, privacy and terms of use

A native of St. Louis Missouri, Boyd holds a Bachelor of Arts from the University of Virginia and a Master of Fine Arts from Carnegie-Mellon University. His 40-year career in the theatre was capped by 18 years as Director of Design and Technology for the Opera Company of Philadelphia until retirement in 2011. His scenic designs have appeared in 190 productions by 78 opera companies throughout North America. A resident of the New Jersey Pine Barrens for over 30 years, Boyd's free Garmin maps of that region date back to 2008 and have been downloaded over 65,000 times at gpsfiledepot.com.

The boydsmaps.com domain was registered in 2010 and the public site debuted in 2013 with a LIDAR-based map of Pine Barrens terrain using the Google Maps API. In the following years, our Garmin maps were gradually discontinued as we felt their format was too limited and their devices too expensive. For awhile, boydsmaps offered downloadable maps for smartphones but ultimately discontinued these as well. With so many different map formats, we used the open source Mobile Atlas Creator as a distribution format. But it just seemed too buggy and confusing, limiting the audience.

By 2019, we realized that browser-based maps could reach a much larger audience and online.boydsmaps.com launched, followed by mobile.boydsmaps.com for smartphones. By 2021, all downloadable maps were finally discontinued and the separate subdomains were merged into a single web app at boydsmaps.com.

In 2022, over 200 remotely-hosted maps were available, including the full suite of commercial products from here.com and mapbox.com. Several specialized apps were added in 2023, including MapSync, the 3d terrain viewer and PinesXT. Locally-hosted maps on the boydsmaps server increased from 80 megabytes to a terabyte by 2023, growing to two terabytes during 2024.

January 2024 marked a big change with the discontinuation of maps from here.com and mapbox.com. These maps were on a trajectory to exceed their monthly quotas of free data which would have resulted in significant charges. Unfortunately, discontinuing these maps made it impossible to properly cover the entire world, so our focus began shifting to the United States.

In early 2025, a major source of remotely-hosted maps made some changes that prevented access from boydsmaps. Although it may have been unintentional, it highlighted a basic problem with maps that are hosted on remote servers beyond our control. The maps were subsequently discontinued and replaced with local versions hosted on our own server. This caused us to re-think our mission and the sources of our maps.

Above all, we want boydsmaps to offer a good user experience with unique maps that load fast and are always available. You should be able to leave the menu open and "channel surf" through the maps. That's difficult when maps are hosted on remote servers with inconsistent performance and changing configurations, so we're transitioning away from them in favor of maps hosted on our own server. Practically speaking, maps require a lot of expensive disk space which limits the geographic area we can cover. But we'd rather do a good job serving a small region than a mediocre job on a big one.

We have decided to focus on the Northeastern United States, which is home to over 65 million people and a popular tourist destination. In coming months, expect more maps of the Northeast while most remotely-hosted maps will be gradually phased out. We do plan to continue offering maps from USGS servers however (as long as performance remains acceptable).

The current inventory of maps hosted on the boydsmaps server is summarized below, these maps are shown in color on the menu. We'll be working to expand the smaller maps to larger regions throughout 2025 and locally-hosted maps will grow to over three terabytes.

7/4/2025
To celebrate Independence Day we released the Landscape of the United States series, showing the changing face of America in 9 maps from 1985 - 2024. Also introduced the new multi-colored map menu.

6/15/2025
Expanded the USGS 24k DRG Topo to cover the entire Northeast US region - a total of over 4000 USGS 7.5 minute quadrangles (more than 7 million map tiles).

5/26/2025
Added a new mid Atlantic 24k DRG Topo Map based on the Digital Raster Graphics standard used by the USGS to create their first online topo's during 1995-1998.

5/22/2025
Added a blue-tinted 250k basemap to the Kobbe 1889 Topo to fill in the blank areas on this irregularly-shaped map. Also intoduced the Terraserver legacy link translator for opening dead links to the Microsoft Terraserver USA website, which no longer exists.

5/10/2025
Expanded the NJ 2006 NAIP imagery to cover the entire mid-Atlantic region (about 5 million map tiles). Changed the map menu: when it's open, it now updates in realtime to show availability as you drag the map around.

4/23/2025
Expanded the NJ 2010 NAIP imagery to cover the entire mid-Atlantic region (about 5 million map tiles). Also introduced new, simplified map menu options.

4/6/2025
Added level 16 coverage, doubling the resolution of the USGS digital topo map

When a map is displayed on the screen, your browser requests a series of image tiles from the map server. These tiles are logged along with the IP address that requested them. This data is only logged when you view maps that are locally hosted at boydsmaps.com.
