Super-resolution mapping (SRM) is an ill-posed problem, and different SRM algorithms may generate non-identical fine spatial resolution land-cover maps (sub-pixel maps) from the same input coarse spatial resolution image. The output sub-pixels maps m... Read More about Improving super-resolution mapping through combining multiple super-resolution land-cover maps.

ISPRS International Journal of Geo-Information, 5(5), 55. https://doi.org/10.3390/ijgi5050055

Citizens are increasingly becoming an important source of geographic information, sometimes entering domains that had until recently been the exclusive realm of authoritative agencies. This activity has a very diverse character as it can, amongst oth... Read More about Crowdsourcing, citizen science or volunteered geographic information?

Super-resolution mapping (SRM) is a technique for generating a fine spatial resolution land cover map from coarse spatial resolution fraction images estimated by soft classification. The prior model used to describe the fine spatial resolution land c... Read More about Learning-Based Superresolution Land Cover Mapping.

A Superresolution Land-Cover Change Detection Method Using Remotely Sensed Images With Different Spatial Resolutions (2016)
Journal Article
Li, X., Ling, F., Foody, G. M., & Du, Y. (2016). A Superresolution Land-Cover Change Detection Method Using Remotely Sensed Images With Different Spatial Resolutions. IEEE Transactions on Geoscience and Remote Sensing, 54(7), 3822-3841. https://doi.org/10.1109/TGRS.2016.2528583

The development of remote sensing has enabled the acquisition of information on land-cover change at different spatial scales. However, a trade-off between spatial and temporal resolutions normally exists. Fine-spatial-resolution images have low temp...

Geographically weighted evidence combination approaches for combining discordant and inconsistent volunteered geographical information (2016)
Journal Article
Comber, A., Fonte, C., Foody, G. M., Fritz, S., Harris, P., Olteanu-Raimond, A.-M., & See, L. (in press). Geographically weighted evidence combination approaches for combining discordant and inconsistent volunteered geographical information. Geoinformatica Polonica, 20(3), https://doi.org/10.1007/s10707-016-0248-z

There is much interest in being able to combine crowdsourced data. One of the critical issues in information sciences is how to combine data or information that are discordant or inconsistent in some way. Many previous approaches have taken a majorit...

The scale of VGI in map production: a perspective of European National Mapping Agencies (2016)
Journal Article
Olteanu-Raimond, A.-M., Hart, G., Foody, G. M., Touya, G., Kellenberger, T., & Demetriou, D. (in press). The scale of VGI in map production: a perspective of European National Mapping Agencies. Transactions in GIS, https://doi.org/10.1111/tgis.12189

The perspective of European National Mapping Agencies (NMA) on the role of citizen sensing in map production was explored. The NMAs varied greatly in their engagement with the community generating volunteered geographic information (VGI) and in their...

Impacts of species misidentification on species distribution modeling with presence-only data (2015)
Journal Article
Costa, H., Foody, G. M., Jiménez, S., & Silva, L. (2015). Impacts of species misidentification on species distribution modeling with presence-only data. ISPRS International Journal of Geo-Information, 4(4),

Spatial records of species are commonly misidentified, which can change the predicted distribution of a species obtained from a species distribution model (SDM). Experiments were undertaken to predict the distribution of real and simulated species us...

An assessment of citizen contributed ground reference data for land cover map accuracy assessment (2015)
Journal Article
Foody, G. M. (2015). An assessment of citizen contributed ground reference data for land cover map accuracy assessment. ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2(3/W5), https://doi.org/10.5194/isprsannals-II-3-W5-219-2015

It is now widely accepted that an accuracy assessment should be part of a thematic mapping programme. Authoritative good or best practices for accuracy assessment have been defined but are often impractical to implement. Key reasons for this situatio...
