In 1982, Senior Park Historian Kathleen Georg Harrison analyzed photographs and proposed the location in [[Evergreen Cemetery (Adams County, Pennsylvania)|Evergreen Cemetery]], but she has not published her analysis. Speaking for Harrison without revealing details, two sources characterized her proposed location as "on or near [the] Brown family vault" in [[Evergreen Cemetery (Adams County, Pennsylvania)|Evergreen Cemetery]].<ref>{{cite book|last=Wills|first=Garry|title=Lincoln at Gettysburg: The Words That Remade America|url=https://archive.org/details/lincolnatgettysb00will|url-access=registration|year=1992|publisher=Simon and Schuster|location=New York|isbn=978-0-671-86742-3|pages=[https://archive.org/details/lincolnatgettysb00will/page/209 209–210]}}</ref><ref>{{cite web|last=The Washington Times|title=Disproving Many Historical 'Facts'|website=[[The Washington Times]]|url=http://www.washingtontimes.com/news/2008/apr/19/disproving-many-historical-facts/?page=1|access-date=June 17, 2013}}</ref>

In 1995, William A. Frassanito, a former military intelligence analyst, documented a comprehensive photographic analysis, which places the location of the platform with the position of specific modern headstones in [[Evergreen Cemetery (Adams County, Pennsylvania)|Evergreen Cemetery]]. According to Frassanito, the extant graves of Israel Yount (died 1892)({{Coord|39|49.180|N|77|13.845|W| type:landmark_region:US-PA_dim:30|name=grave of Israel Yount (d. 1892)}}), John Koch (died 1913)({{Coord|39|49.184|N|77|13.847|W| type:landmark_region:US-PA_dim:30|name=grave of John Koch (d. 1913)}}), and George E. Kitzmiller (died 1874)({{Coord|39|49.182|N|77|13.841|W| type:landmark_region:US-PA_dim:30|name=grave of George E. Kitzmiller (d. 1874)}}) are among those which occupy the location of the 1863 speaker's stand.{{sfn|Frassanito|1995|p=160-167}}

====3D photo-rendering and -animation====
Over a course of many years, Christopher Oakley, an assistant professor of new media at the [[University of North Carolina at Asheville]] and his students have labored to produce and relentlessly perfect "a lifelike virtual 3-D re-creation of Lincoln delivering the Gettysburg Address" as part of the Virtual Lincoln Project.<ref>{{cite web | url = https://www.smithsonianmag.com/history/will-the-real-abraham-lincoln-please-stand-up-3431/ | title = Will the Real Abraham Lincoln Please Stand Up? | last = Lidz | first = Frank | publisher = Smithsonian Magazine | access-date  = 22 November 2022}}</ref> One result concluded, “Placing the Platform: Using 3D Technology to Pinpoint Lincoln at Gettysburg” was presented on November 18, 2022, at the Lincoln Forum XXVII in Gettysburg.<ref>{{cite conference |url=https://www.c-span.org/video/?524210-2/2022-lincoln-forum-photo-lincoln-gettysburg |title=Photos of Lincoln at Gettysburg-Placing the Platform:Using 3D Technology to Pinpoint Lincoln at Gettysburg |last1=Oakley |first1=Christopher |date=November 18, 2022 |publisher=[[C-SPAN]] Video Library |location=Gettysburg, PA |conference=Lincoln Forum XXVII}}</ref><ref>{{cite web | url = https://www.thelincolnforum.org/2022-symposium-schedule | title = Lincoln Forum XXVII: "Lincoln in the Civil War White House: The Politics and Personalities of a Union Divided" | publisher = The Lincoln Forum | access-date = 22 November 2022 | archive-date = November 22, 2022 | archive-url = https://web.archive.org/web/20221122230821/https://www.thelincolnforum.org/2022-symposium-schedule | url-status = dead }}</ref>

As a starting point, the project modeled the topography around Cemetery Hill, the Gatehouse at Evergreen Cemetery, and the documented positions of nonextant objects, which appear in photographs, including the poplar tree, the flag pole, and the Duttera House among them, using 3-D animation software [[Autodesk Maya|Maya]]. The platform and its occupants also were modeled. The approximate positions of the cameras were placed into the 3-D environment, and the overall model was iteratively refined. By reproducing the appearance of the four known photographs, taken distantly from one another in 1863, Lincoln and the platform have been placed in virtual reality.

Oakley's model shows the platform straddling the iron fence between the Soldiers' National Cemetery and Evergreen Cemetery. It increases the size of the platform and changes its shape from rectangular, as previous researchers have maintained, to trapezoidal. The speaker's position occupies a portion of the platform over the grounds of the Soldiers' National Cemetery.<ref name=Oakley>{{Cite news |last=Schuessler |first=Jennifer |date=2022-11-18 |title=A Lingering Gettysburg Battle: Where Did Lincoln Stand? |work=[[The New York Times]] |url=https://www.nytimes.com/2022/11/18/arts/lincoln-gettysburg-address-oakley.html |access-date=2022-11-20}}</ref>

William Frassanito's analysis is based on two of the four photographic perspectives, which were employed by Oakley to validate his 3D model. Frassanito assesses one of his sources, saying, "This view [by Weaver] was probably not taken from the second-story window of the gatehouse itself."{{sfn|Frassanito|1995|p=160}} Via enlargement of a Gardner photograph (taken from the opposite direction), John J. Richter may have identified a photographer with a camera in this exact window, thereby weakening the contribution of the Weaver photograph to Frassanito's conclusions.<ref>{{cite web| url = https://abrahamlincolnatgettysburg.wordpress.com/finding-other-photographers-at-the-gettysburg-soldiers-cemetery-dedication-on-november-19-1863/| title = Abraham Lincoln At Gettysburg: Finding Photographers and their Equipment in Gettysburg Soldiers' Cemetery Photos| last = Heberton IV| first = Craig| date = November 17, 2013| publisher = WordPress| access-date = 22 November 2022}}</ref> Oakley's proprietary 3D model utilizes the position of Weaver's camera as suggested by Richter.
