CyberGIS: A synthetic review and Integration Roadmap (Wang et al. 2013)

7 October 2017 - 4:24pm
This paper was a challenging read as it focused on areas of GIS I had limited to no knowledge on. CyberGIS seems like a very ambitious field in its aims to incorporate all these tools of GIS into one convenient package. One of the issues I have with this however, is the feeling of possibly […]

Geospatial Agents, Agents everywhere! (Sengupta & Sieber, 2007)

2 October 2017 - 10:53am
This paper gave a comprehensive overview of AI, agents, the role of these in GIScience. I found in many ways this overview brought up topics from the ‘GIS: Tool or Science’ debate, as the paper seemed to bring up AI a lot, when the real topic at hand were agents possibly due to the instant […]

Automated Extraction of Movement Rationales (Sengupta et al., 2018)

2 October 2017 - 10:51am
I very much enjoyed this paper by prof. Sengupta as it brings some very new age technology of Agent-Based-Models (ABMs) in a very natural and almost humble way. The methodology for this paper was very interesting as it used pixel based classification to derive land cover (remote sensing), points and buffers (vector files), and DEMs […]

Automated Extraction of Movement Rationales (Sengupta et al., 2018)

2 October 2017 - 10:45am
In this paper, the authors present the rationale of animal movements, and show how to extract “rules” from movement data by applying agent-based models (ABMs). To understand the movement of individual organism, the authors refer to four components including internal state, motion capacity, navigation capacity and external factors, which proposed by Nathan et al. (2008). […]

Automated Extraction of Movement Rationales for ABMs

2 October 2017 - 10:04am
I was left with several questions about the observation data. It was collected over a 1.5 year period, yet locations were only observed every 15 minutes. There was no explanation of the daily frequency of observation. If the observation is not continuous, can’t “movement” only be observed between the 15 minute intervals? Was the 75% […]

Thoughts on ‘ Geospatial Agents, Agents Everywhere…’ (Sengupta, Sieber 2007)

1 October 2017 - 11:24pm
I liked how this review delineated very specifically the difference between Artificial Life Agents and Software Agents because I was quite ignorant about the latter before. What struck me about the four conditions necessary for classification as an intelligent agent, each criteria is the result of many different interacting subfields. For example, the possession of […]

Sieber and Sengupta: Geospatial Agents Everywhere

1 October 2017 - 10:29pm
Sieber and Sengupta’s paper on geospatial agents situates artificially intelligent agents within the context to GIScience. This spatial context results in the geographically oriented applications of the concept referred to as ‘Artificial Life Geospatial Agents’ (ALGA’s) and ‘Software Geospatial Agents’ (SGA’s). Effectively, these agents are technologies that allow GIScientist to be more efficient in their […]

Geospatial agents or AI agents? On Sieber and Sengupta, 2007

30 September 2017 - 8:13pm
Sengupta and Sieber (2007) present an overview of geospatial agents and situate the concept within existing literature. The concept of an intelligent agent was completely new to me before reading this article. Despite the definitions provided, my lack of knowledge about AI made it difficult for me to grasp many of the concepts outlined in this […]

Sengupta and Sieber – Geospatial agents

30 September 2017 - 5:47pm
According to Woolridge and Jennings (1995), an artificial intelligent (AI) agent must be able to  (1) behave autonomously; (2) sense its environment and other agents; (3) act upon its environment; and (4) make rational decisions. For geospatial agents, this environment is (or is a subset of) ‘the earth’. Consequently, a geospatial agent may also have access to other geographic data, […]

Automated Extraction of Movement Rationales for ABMs

29 September 2017 - 4:06pm
This essay presented an introduction to me for ABMs. Through the regular snapshot of a red colobus monkey’s positioning on GPS, both accounting for time and space, we can make soem strong empirical studies into the nature of movement for the monkeys. Up onto this point, most theories on movement whether they be animals or […]

Geospatial Agents, Agents Everywhere… Sengupta and Sieber (2007)

28 September 2017 - 8:46pm
I thought this review was an interesting contrast to the discourse presented in the Wright et al. (1997) article on GIS as a tool or science. There seems to have been a transition from GIScience arguing for its own existence to asserting its domain over established concepts. At first, I was a little skeptical of […]

On Sengupta et al. (forthcoming 2018), movement, and ABMs

28 September 2017 - 6:57pm
I thought Sengupta et al.’s article, “Automated Extraction of Movement Rationales for Building Agent-Based Models: Example of a Red Colobus Monkey Group” (forthcoming 2018), was incredibly interesting. “Automated Extraction” discusses the use of agent-based modeling (ABM) strategies in simulating red colobus monkey groups’ movements “across space and time and predict[ing] environmental outcomes” (2). Utilizing the […]

Automated extraction of movement rationales for building ABMs: Sengupta et al. (2018)

28 September 2017 - 1:43pm
I found both of these articles really fascinating, and found it helpful to understand the theories and differences between the ALGAs and SGAs presented in Sengupta and Sieber (2007), especially in analyzing the ABM presented in Sengupta et al. (2018). Sengupta et al. (2018) use field-recorded data on Red Colobus monkey location and movements in […]

Public Participation on the Geospatial Web (2016)

25 September 2017 - 10:41am
This article concludes that unitizing participation eventually hurts data quality.  Sieber also concludes that in many cases, VGI is an imperfect method for lack of traditional expertise. The cases examined in this article fall under the same umbrella of VGI applications for the public good, or specifically for narrowing the G2C relationship. The cases also […]

PPGIS: A Lit Review and Framework (Sieber, 2006)

24 September 2017 - 11:59pm
In this paper, Sieber (2016) review the history of Public Participation Geographic Information System (PPGIS), explore four themes of it including place and people, technology and data, process, and outcome and evaluation. In my perspective, it is no doubt that PPGIS has been socially-constructed. However, there are some critical questions I think worth discussing. Since […]

PPGIS Literature & Framework

24 September 2017 - 11:22pm
The idea of PPGIS may appear relatively abstract when compared to the run-of-the-mill public participation (PP) process but at its core it is striving to accomplish the same thing. It is unbiasedly taking stakeholders into consideration for projects by giving them all the same information they would have in a regular PP process but with […]

PPGIS: Literature Review and Framework, Sieber (2006)

24 September 2017 - 8:42pm
Sieber’s article establishes the historical context for PPGIS, and explores a framework for evaluation based on themes found throughout the PPGIS literature. It’s an interesting point that the term “participation” itself suggests the need for some intermediary. If PPGIS is to be viewed as a decision making tool, I would imagine that the typical role […]

Sieber et al. (2016) – Geoweb for PPGIS

24 September 2017 - 6:11pm
Web-based geospatial tools (Geoweb) have opened up a wealth of opportunities for Public Participation GIS (PPGIS). With emphasis on usability and design, the Geoweb consists of platforms where everyday users can view, collect and share geospatial data. For governments, this provides potential new sites for interaction  with citizens. In this paper, Sieber and colleagues explore […]

Public Participation in the Geospatial Web

24 September 2017 - 4:15pm
The way that neography is presented in this article sounds incredibly exciting. It presents itself as a radical counterpoint to the ubiquitous and predatorial cultivation of data from powerful private interests. The organizations discussed in this article all seemed to have altruistic measures with the reasons given for volunteer participation also reflecting that point of […]

Public Participation in the 21st Century: Now on a Map! (Sieber et al. 2016)

24 September 2017 - 2:10pm
This paper’s truly interesting in that it addresses the philosophical questions of why people contribute anything, as well as the thought process that goes into contributions, and what makes them valid. I found that grounding of the geospatial web (a brand new topic) to its fundamental core, which is civic participation dating back to ancient […]
