Questions related to Environmental Geography
I have some environmental covariates derived from the digital elevation model (slope, gradient, channel network distance, etc.) in raster format.
I want to identify areas of similarity between the covariates and somehow identify the smallest possible size area (or areas) to serve as a reference area.
- Soil data points will be collected to create predictive models in this reference area.
- The predictive models developed in the reference areas should fit when extrapolated to regions outside the reference area.
- Therefore, the covariates will cover this external area.
Copyright issues are a secondary concern as their principal application will fall under the terms of 'fair use'
I have attached the OSM map of Pannipitiya, Sri Lanka. So looking at the map, what kind of geographical questions you can ask?
To me, the following came to my mind
1. What are the places where house dwellers can walk and reach within 1 minute (600 m ?) ?
2. What is the calmest and quiet place to meditation?
Working with climate/Geographical data, there is some moment you definitely need to analyze data with programming language or software tools. In that case which one you will prefer more to do that task?
- Other( Please mention the name with details)
Everyone knows, the fast changing climatic condition with altered physical factors due to various anthropologic activities. Humans are unable to handle the issue of climate change due to growing needs and population. So, how nature will resolve the issue of climate change without human interference?
I am particularly interested in conceptual literature and pieces of research that aim at advancing the human geographic debate on (local) climate governance. Thank you very much!
Dear GIS experts,
Please, I need your assistance to draw the map of my study sites located at Arusha and Kilimanjaro regions of Tanzania (Eastern Africa). Please, I simply need the map of the two regions (Arusha & Kilimanjaro) showing my study sites with the following coordinates
First study site: Latitude 3º21’50.08”N and Longitude 36º38’06.29”E in Arusha region (DMS latitude longitude coordinates: 3°22'0.01"S, 36°40'59.99"E)
- Second study site: Latitude 3°13’59.59”S Longitude 37°14’54”E in Kilimanjaro region (DMS latitude longitude coordinates: 3°21'0"S, 37°19'59.99"E)
Please, I need your kind assistance on this; be it by advice or draw the map and sent to me. I highly appreciate your kind gesture in advance. Attached is a copy of the raster map of the two region but I need to locate my study sites. Thank you
Infectious ecology is a new line of research. In a clear way, it was formulated in 2017. In 2018, some works were carried out that showed the significance and real novelty of this scientific approach. On its basis, new theoretical interpretations of a whole range of infectious diseases can be given.
The case of KDD is not unique. There are a considerable number of infectious novelties that are difficult to understand in the dominant scientific terms. An example would be ebola. In the infectious ecology, an attempt is made to re-state the problem and to find a new solution for the KDD.
The basic idea is that we are dealing with another manifestation of the discrete activation of the pathogenic properties of microorganisms. As in many other cases, the cause is a change in soil geochemistry. That it is a pretext for the manifestation of the pathogenic properties of Phytophthora agathidicida. This is usually associated with agriculture and anthropogenic changes.
Christian Nold (2009) in his book of essay Emotional Cartography aims to
explore the political, social and cultural implications of visualising intimate biometric data and emotional experiences using technology.
In my research (http://www.pocitovemapy.cz/index-en.html) I work with term emotional mapping, but I have been told by some other researchers, readers and reviewers, that emotional mapping is not the correct term, as emotions is not what is being mapped.
I usually ask people to identify places on the map, where they feel afraid (mapping of safety), where they "like it" (spatial preferences), but also places where they spend free time, or places where it is dirty (environment pollution, etc.).
Which term, would you suggest for this kind of subjective mapping - would it be emotional maps or maps of perceptions? And what do you think is the main difference?
I have list of ~3000 geographical locations from various parts of India. I want to find out their Latitude and Longitude co-ordinates. I want to know if there is any tool / software that will together find out the co-ordinate and put the location on the map.
I have several layers in my overlay, but when I run it they show for the whole area they have data for (global), whereas I would like them to display their results only within the area of a polygon I have created. Does anyone have any ideas as to the code required for this?
From January 2014 to December 2016, I conducted monthly field trips in three different areas of Dhaka city, Bangladesh to investigate how butterflies survive in an inner-city habitat. I have found that the species richness (I did not count the species abundance) is declining with time.
Presently, I have:
* monthly species-specific data of three continuous years (36 continuous months) of the three different areas
* Four environmental variables (temperature, rainfall, humidity and sunshine hours)
* Pollution level
* IUCN Red List status
* Land-use analysis of these three different areas
Now, I am really confused considering the proper way to link these pieces of information! Could anyone of you please share some ideas?
Urgent - trying to find a program that will convert a scanned pollen diagram into either graphs, a digital, clearer pollen diagram or data tables.
Can it help to understand adaptive strategies of them?
Thanks for your answers
From January 2014 to June 2016, through the continuous field trips, I have listed all those butterflies which were spotted. Now, I have analysed the land area management of Dhaka city which contains over 17 million inhabitants. The total species number is 136 and a good number of them are Endangered and Vulnerable according to regional IUCN Red List 2016. How can I synchronize these data? Is it possible to make a conservation management plan with the help of this research? Please help..
Dry season Landsat data constitute my database for the study.
The area is about 20km X 20km.
I know this is question highly depended on geographic location, but is there an average deposition of NH4 from the atmosphere into a body of freshwater? I'm specifically looking for a reference that gives the amount of NH4 deposited into a litre (or m2- surface area) of water per year. I'm looking for references ideally from the UK.
I'm specifically looking for references that report atmospheric deposition, independent of dust/rain/bird droppings etc.
Any help or advice pointing me in the right direction will be very much appreciated.
I would like to know if any simple bioclimatic index has been proposed (as Humidex or Heat Index for mixing the effect of temperature and humidity) to include the deleterious effect of strong winds when T > 37°C or so. I know that some indices already include the cooling effect of strong winds (as net effective temperature) when T is low but I am rather interested by the warming effect of winds. I add that I am looking for a synthetic index (not as complex as UTCI for example).
Thank you in advance
Relating location of the Redom River in NW Africa. I know only the former name of this river and I need for any information about its current name and geographic position (coordinates)
The great alluvial Plain of Catania (Piana di Catania) is situated in the East of the mediterranean island of Sicily. Basically two rivers flow there along the sides of the plain into the sea: Simeto and Gornalunga. The region is absolutely ideal for bronze age water engineers to build the usual bronze age water engineering. Yet, I cannot find any academic work on this. Sicilian archaeology is concerned only with the Greek era or with single settlements, not with landscape archaeology, as it seems. Any helpful hint is welcome!
What is the mathematical function that determines the solar radiation received by the area defined by two parallels and two meridians depending on latitude? How can the tilt of the axis of rotation affect the received radiation?
I know of RSI, THI, ET, PMV, AT(apparent temperature) and PET. I will appreciate indicies that is applicable in the Tropics.
