    Distributed Monocular SLAM for Indoor Map Building
    (Hindawi, 2017) Egodagamage, Ruwan; Tuceryan, Mihran; Computer and Information Science, School of Science
    Utilization and generation of indoor maps are critical elements in accurate indoor tracking. Simultaneous Localization and Mapping (SLAM) is one of the main techniques for such map generation. In SLAM an agent generates a map of an unknown environment while estimating its location in it. Ubiquitous cameras lead to monocular visual SLAM, where a camera is the only sensing device for the SLAM process. In modern applications, multiple mobile agents may be involved in the generation of such maps, thus requiring a distributed computational framework. Each agent can generate its own local map, which can then be combined into a map covering a larger area. By doing so, they can cover a given environment faster than a single agent. Furthermore, they can interact with each other in the same environment, making this framework more practical, especially for collaborative applications such as augmented reality. One of the main challenges of distributed SLAM is identifying overlapping maps, especially when relative starting positions of agents are unknown. In this paper, we are proposing a system having multiple monocular agents, with unknown relative starting positions, which generates a semidense global map of the environment.

    "How Others Have Built": A Sketch of Indianapolis Construction and Demolition Patterns
    (2018-12) Ryan, Jordan B.; Monroe, Elizabeth Brand; Barrows, Robert G.; Cramer, Kevin; Selm, William
    This thesis argues that an architectural surveying methodology via newspaper sampling offers new insight historic preservationists can use to more efficiently predict demolitions. Using data collected from the “Home Builder’s Department” section of the Indianapolis Star, this study compiles architectural information on 425 structures, mostly single-family and duplex residences, built between 1909 and 1926. Engaging with the historiographical themes of public history and architectural history as well as methodological components of historic preservation and digital humanities, the data-centric model relies on a collection of sampled newspaper articles, which were analyzed for specific information, compiled into a data repository with supplemental research, and then incorporated into the ArcGIS program for interpretation. The project provides a synopsis on early twentieth century building trends in Indianapolis and offers implications regarding the role that factors such as building type, geographic location, federal and municipal historic district protections, architectural style, and exterior building material or cladding play in predicting demolitions. Beyond these predictive results, this study also suggests a city-wide surveying methodology for organizing and analyzing large quantities of historic architecture for preservation planning initiatives.

    Indianapolis in Maps: Now and Then
    (2006-10-02T17:58:41Z) Palmer, Kristi L.
    This kit contains all the documents needed to replicate the activity, "Indianapolis in Maps: Now and Then" which is a 1-2 hr. program that introduces learners to the benefits of maps as tools for discovering a city’s (and its people’s) history. Using map navigation skills, participants will be provided with a list of well-known present day landmarks in Indianapolis. They will locate these sites on a current map of downtown Indianapolis and using the information found here (addresses, street crossings, site surroundings) locate the same site on the Sanborn Fire Insurance Map from 1887 or 1898. Some landmarks will be the same, showing learners that many present-day landmarks in Indianapolis existed over a hundred years ago. Participants will also find that many of the same buildings still exist but that they are now used for different purposes. And finally the class will also find that some areas of downtown have completely changed their look and purpose. In addition to finding the specific landmarks listed the participants are also encouraged to explore the maps in-depth (especially the older maps) and record anything that stands out to them, is interesting. While students will work in groups or individually on the formal worksheet activity, the class will come together at the end to share their discoveries and what these discoveries might infer about the city, its people, and its history.
