Association of Moving Image Archivists Conference 2015

In late November, I attended the annual conference of the Association of Moving Image Archivists (AMIA) in Portland, Oregon. Here are a few of the highlights.

HACK DAY

Once again, AMIA partnered with the Digital Library Foundation (DLF) on a one-day event where archivists and developers could work together on digital problems. This year’s award-winning projects were: Continue reading

The 2015 Vancity Theatre Screenings are now on YouTube

We had another successful run showcasing our moving image series at the Vancity Theatre this past November. Every year, we are thrilled to see the enormous interest our screenings generate. We are aware that due to sellouts, the theatre must turn away many hopeful theatre goers. To accommodate as many people as possible, each year we will continue to hold multiple screenings, and rerun previous years’ screenings. You can also view all past shows on our YouTube channel, including this year’s Vancouver – A Distant Mirror and Reflecting the City (Redux). Please note that online content will not include pre-screening projected snipes and presentations, or any commentary or music accompaniment. For more information about the most recent screenings, please visit our previous post.

We hope to see you at our 2016 show!

Listed below are the four sections of Vancouver – A Distant Mirror, and the individual archival films featured. Continue reading

Putting the Goad’s 1912 Plan into Open Historical Map

We’ve had great response to making Goad’s 1912 Fire Insurance map available as a Vanmap layer and as downloadable open data. We received a request to make it available in a different type of service so that the information can be used a variety of ways. As a result of all the feedback, we plan to contribute the information through Open Historical Map and the Province of British Columbia’s innovative BC Developers’ Exchange is collaborating with us to help make it happen.BCDev-home

 

BC DEVELOPERS’ EXCHANGE

The BC Developers’ Exchange is an experiment to find ways that help the public and private tech sectors innovate and collaborate. They are helping share code created by BC’s public sector and collaborating with vendors to make that code better. The Exchange is also supporting the sharing and re-use of other digital resources.

In response to your suggestions, we sponsored development of an improved date search. It’s in Advanced Search, on the left sidebar. Continue reading

Our digitized maps are now available in TIF format

This post is of special interest to the mapping community and may be too technical for some researchers.

We digitize all of our images—photographs, maps and text—as TIFF master files, which are processed through our digital preservation system and preserved in our secure digital storage. We have been making all our digitized images available to researchers in our online search in JPG format. It allows us to make high-resolution files available in a fairly small size so they can be opened and viewed quickly. The quality is good enough for most uses.

Clicking on this map image will bring up the high-resolution JPG version, which can then be downloaded.

The mapping community has told us that JPG files are not good enough for their use. TIF or PNG formats give the best results when manipulating files in mapping software. The original scanned files, without any compression artifacts, would be the most useful.

To support the use and re-use of these valuable resources by everyone, we’re making losslessly compressed versions of the original TIFFs of our scanned maps available for download. We’ve added a link to the TIFF of a map to our online search as part of the descriptive record for that map.

Scroll down to find the link to the TIFF on the City’s FTP site.

So that you can verify that the file downloaded correctly and completely, we’ve included the full file size and the MD5 checksum.

We’d like to thank City Information Technology, whose recent upgrade of the City’s FTP site made it possible for us to make the files available this way.

1912 historical layer now available in Vanmap

With funding from the City’s Chief Digital Officer and in collaboration with the City’s GIS and Open Data teams, there is now a Vanmap layer made from a mosaic of plates from Goad’s 1912 Fire Insurance Plan. You can find it in Vanmap’s Aerial Imagery category. The data has also been released as part of the City’s Open Data Catalogue. Cropping and georectification of the scanned images was done by McElhanney.

Historical zoning maps available

We’ve made a group of zoning maps available online. These are frequently consulted by our researchers, so we’ve made them easily available to everyone.

The maps were published:

Created by the City of Vancouver Planning Department, the maps allow you to see the permitted uses of land over time. These maps are used as a first step for an environmental assessment of a site. They are also useful for those studying the history of urban planning.

Map of New Westminster District – a collaboration

We have a very large and rare 1905 map in our holdings that was dirty and falling apart. Last year, we collaborated with the Land Title & Survey Authority of British Columbia (LTSA) and the BC Archives to conserve and digitize it. This is the story of why that conservation treatment happened and how it was done.

The 1905 Map of New Westminster District is almost 1 metre wide and over 2 metres long. It shows District Lots and other divisions of land for all of Metro Vancouver and as far east as Hope. Continue reading

Moving Historical Geodata to the Web

In nearly every case, “historical geodata” means a paper map. Digitizing that map gives us an image of a paper map. While an image can be useful, historical maps turned into actionable data are much more useful. Moving geodata from paper to electronic data can be complicated and involve many actions, including:

  • Describe the map accurately, preferably using standard terms
  • Digitize the map
  • Georectify the digitized image (associate points in the image with their geocoordinates, for example, so that the image can be positioned on OpenStreetmap or Google Maps exactly where it belongs)
  • Extract image features—such as polygons, text, or contour lines—as digital layers

From November 5-7, 2014, I attended a meeting of 54 people from three continents at the New York Public Library called Moving Historical Geodata to the Web. This meeting, including expenses for attendees, was funded by the Alfred P. Sloan Foundation. We were the only archives and the only Canadian institution represented. Continue reading

Pacific National Exhibition photographs are now online

Thanks to funding from the British Columbia History Digitization Program, we’ve recently completed a project to digitize over eight thousand images from the Pacific National Exhibition fonds that you can easily view and re-use. In addition, we’ve digitized another 874 images that are under copyright to other parties, but which can be viewed at the Archives. The dates range from 1914 to 1980.
