    Not a great experience. Darko completed 90% of the project and, in general - that work was very good.However, the project duration was 8 days. At 25 days past the project deadline he requested a 90% increase in the price - for work that was within the scope of the project. At 30 days past the deadline he asked for a milestone payment.Once receiving the payment he notified me that he wasn't capable of completing the project.Darko would do well to develop some business ethics and professionalism before he develops any more code.

    ReflectColor's reply:

    Very unpleasant experience. Towards the end of the project the client has significantly expanded the project specification, when I told him that this additions request a budget increase, I received several messages written in indecent manner, after which I decided to stop cooperation.

    Project Description:Build an interactive Google Map displaying many thousands of locations with the ability for a user to add a new location of their own.

    We are civilian drone pilots in the UK. We are taking our licence at the end of May. we have fixed wing and multi rotor unmanned aircraft equipped with cameras. We will be collecting air photos for archaeology, mine/stock pile volumetrics, precision agriculture and construction. We want to concentrate on flying the drones and are looking for a partner who would like to work with us. Can you create ortho-mosaics from geo tagged photos, obviously we have ground control points taken with GPS, and stockpile volumetrics is also a service we would like to offer.

    I will give you a dataset (spreadsheet or SQL script) with 10 sample data rows. Each row will have (a) a street address in South Florida USA, (b) a &quot;name&quot; of the location, and (c) a signed integer. You make a solution using Google Maps API as follows (a) The web page has a Google Map of south Florida USA (I will provide you details). (b) OnLoad, the page selects the data from the SQL table.(c) The page puts a &quot;marker&quot; on the Google Map for each address in the SQL table. The marker is an icon with the integer for that address (you can use one color marker for positive integers another color for negatives. See, for example, the map at which is much more graphically complex than I need)(d) MouseOver the marker, and the name and address for the location (from the SQL dataset) is displayed (e) provide me a second page to view, insert, delete, and modify rows from the sql table. (I prefer aspx solutions, but its Google, so just include what technologies you will use in you bid.)

    I need an online map that outlines my sales reps and their territories. I want to put this on our website so customers can see what rep covers their area and get their contact info. I also want to be able to integrate a database of customers so we can do territory specific mailings by zip code.

    We need to display some Google maps which show the location of stores that carry our products. The data to populate the markers on the map will be pulled from an xml file (or similar).I do have a basic version of this already on my website however the code is quite rough and the xml data is only used on the map, not the text listing, making it slower when I need to update details. I&quot;m not happy with the load time or the general layout either. It&quot;s probably best to start afresh.I&quot;m open to layout ideas but I would think initially they choose Australia or rest of world. Click on one and it takes you to the relevant map. The world one can just be like what we have. For Australia there should initially be an overlay so people can choose which state they want, when they click on the state they want the overlay disappears and the Google map shows up and zooms in to show the sort of details we currently have. Each reseller&quot;s details would be in text on the page like we currently do and they would have a custom marker (maybe our logo on a flag or something) on the map too with a bubble that shows the details of that reseller. I would like the text details of the reseller and the marker to be linked so when you click / mouseover one the details pop up on the map and the text listing is highlighted in some way so people can see which one they&quot;ve clicked on. I may not want all details shown in both the bubble and the text listing so would like to be able to choose what is shown where (i.e. separate fields in the xml file for name, address, phone number etc).Finally it would be nice to have a postcode field so someone can enter their postcode and the map highlights the closest reseller (or orders them by distance). This would probably only be for Australia. This is not critical but would be a nice addition if it doesn&quot;t add much more to the cost. Please indicate in your quote whether it includes this feature.

    Hi Engmohamedadel,I would like to develop an application for Mac OSX to convert .JPG, .PNG, .TIFF to BSB (and/or .kap) format.Here is an example of exactly what I would like, however it only runs on early versions of OSX: is a video of the converter working: is the formatter code: is the GeoFormatter: info on what a .kap file is & of what a BSB file is: see ‘BSB File Format – A Brief Description’ : / kap headers application for Windows based: of Windows based converters that do similar things: details on Windows based converter: details:- The zoom lens feature on RasterChart2BSB is not necessary, however zoom of some sort is necessary.- Only datum WGS48 necessary- Latitude & Longitude format only needs to be: 00° 00′ 000″ for north, south, east, west- The converted .kap files are to be read in the (free) viewer: you think this is possible? Can you do it? If so what would be the cost? I look forward to hearing from you.CheersBen

    I need to develop a web based system that allows user to import a file (Excel , csv , txt ) of about 1000-5000 records; each of theme contains, in addition to generic data, a geographic address ( with separated fields for : street, city, province, zip code ) .The system should then verify that the addresses are correct and, in case of ambiguity or error * (see below some of possible errors), suggest (if possible) a correction and show a page where user may accept or modify what system proposed. In addition, system should ( optional feature ) geocode the addresses.Finally, once user has edited and / or accepted all &quot;ambiguos&quot; records, system must be able to export data within a file (Excel , csv or txt) .* Possible errors :- Name of the street typed in a wrong way; eg &quot;Via GaribaldO&quot; (with the &quot;O&quot; at the end) and not &quot;Via Garibaldi&quot;;- name of the street typed in a not completed way; eg &quot;Via Garibaldi&quot; and not &quot;Via Giuseppe Garibaldi&quot;;- generic zip code against the real one (eg 00100 instead of 00179 for Rome ) ;- address Number does not exist ;- Location (Town or City ) wrong (eg, the field &quot;location&quot; is filled out with the name of the village and not with the name of the city) ;- And so on.In practice, the logical steps can be summarized as follows:1. import a file ;2. Verify addresses geographical and propose (if possible) a correction;3. System has to show user ambiguos records and allow him to correct them ;4. Geocode addresses ;5. Export data into a file (with lat - long) .Thank you.Antonio Caramia

Spatial modelling of soil erosion potential in a mountainous watershed of South-eastern Serbia


This work aims at the assessment of soil erosion rate and its spatial distribution in hilly mountainous Nisava River Basin (South-eastern Serbia) with a surface area of approximately 2,848 km2. The study was conducted using Universal Soil Loss Equation (USLE) model due to its modest data demand and easy comprehensible structure. The erosion factors of USLE were collected and processed through a GIS-based approach. Landsat 7 Enhanced Thematic Mapper (ETM+) image and normalized difference vegetation index (ND

Application of USLE, GIS, and Remote Sensing in the Assessment of Soil Erosion Rates in Southeastern Serbia

Polish Journal of Environmental Studies

The assessment of soil erosion rate and its spatial distribution in the hilly-mountainous Nisava River basin was conducted by Universal Soil Loss Equation (USLE) model through a GIS-based approach. A Landsat 7 Enhanced Thematic Mapper (ETM+) image and normalized difference vegetation index (NDVI) were used for the determination of crop management factor. The average annual soil loss was estimated at 13.1 t·ha-1·yr-1, classifying the Nisava River basin under the high erosion rate category. Abou
