New Collections Available in Digimap

As part of the University of Leicester Library subscriptions we subscribe to Digimap, an online map and data delivery service.

We now have two more collections available via Digimap:

Marine Digimap

Marine Digimap offers two types of data.

Firstly, raster nautical charts are derived from UK Hydrographic Office paper charts and chart panels. This chart dataset comes in two versions: Raster Charts and Raster Charts XL, which excludes land-based features so you can add your own.

Secondly, Marine Themes vector data covers all UK waters and is a feature rich dataset derived from authoritative material obtained from the UK Hydrographic Offices, as well as comprehensive source data where available. Marine Themes Vector is engineered into logical data layers for easy loading and efficient use in Geographic Information Systems (GIS). Data attributes have been designed with analysis and querying in mind.

All data is licensed by OceanWise.

Marine data is extensively used in offshore engineering projects, management of marine and coastal environments, marine ecology studies, environmental impact assessments and tourism.

Environment Digimap

Environment Digimap brings easy access to Land Cover data from the Centre for Ecology and Hydrology. Separate datasets are available for 1990, 2000, 2007 and 2015, all national coverages. Also included are Dudley Stamp’s maps of the 1930’s Land Utilisation Survey of Britain.

Make a map of your chosen area of interest using Environment Roam, which also enables the data at any location to be queried, printed and compared side by side with the same data of a different date. Use Environment Download to search and retrieve the data for your area of interest.

The Land Cover data can be used to plan, manage or monitor agriculture, ecology, conservation, forestry, environmental assessment, water supplies, urban spread, transport, telecommunications, recreation and mineral extraction. It is particularly useful when combined with other datasets. Use the land cover data to examine the coincidence of a given species with particular land cover types, make assessments of habitats at risk from a specific development, or look at national distributions of land cover types and how it is affected by other environmental and human factors.

Current examples of the application of the Land Cover Map include detection of changing land cover, landscape management, mapping bracken in the context of health studies (bracken supports ticks carrying human disease), environmental assessments of motorway extensions, and planning of telecommunication lines.

Existing Digimap Collections

These new collections join the existing collections:

Searching ABS Journals in Business Source Premier

In Business and Management Studies, researchers undertaking a literature review sometimes search across a defined group of journals. This is a way of focusing the literature search to make the results more relevant to the questions in hand. Groups are often chosen from the Association of Business Schools (ABS)'s Academic Journal Guide . Read more how about how they put together the guide here . There are several ways to search across ABS journals. Here is how to do it in Business Source Premier, a leading literature database for this subject area. 1. Login into the ABS journal guide. If you have never used it before you will need to create an account. 2. You can use the guide to draw up a group of journals either by using the Rankings information or the Fields. Fields divides up the journals into categories of research focus e.g. Accounting, Finance etc. In this example we will use the Fields. The field we are interested is ‘Operations Research and Marketin

You can now export multiple citations from Google Scholar

You can now export multiple citations from Google Scholar if you have a Google Account. Go to Google Scholar and sign into your Google Account. Conduct your search. Click on the Star icon (Save) under each reference you want to export. Then click on My Library in the top, right of the screen. Select all the references and click on the Export option: Click the Star/Save Icon Choose Export Option To Export into EndNote Choose the EndNote option. Open the EndNote file that is created. The references should automatically import into EndNote. To Export into RefWorks Choose the RefMan option. Save the RIS file that is created. Login to your RefWorks account. Click on the plus (+) button. Choose Import References. Add the RIS file you just saved. Set the file import option to RIS - Reference Manager. Click import and your references will be imported. --- Good Practice Tip: Always check that all the reference information you need has been

Advanced Search Tip: Proximity (Adjacency) Searching

Proximity (Adjacency) Searching vs Phrase Searching When you're searching literature databases you might want to find a phrase. The easiest way to do this is to put the phrase in "speech marks". E.g. "heart disease" This will find that exact phrase - with the words next to each other in that order. BUT... You may be interested in variations on that phrase e.g. heart disease, disease of the heart, diseases of the heart, diseases of the human heart. In that case it might be better to use a proximity/adjacency search - this allows you to find one keyword next to another. Or one keyword within a specified number of words of the other keyword. When using a proximity search the keywords can be in any order. Different Databases Use Different Proximity Operators In Ovid Medline : heart adj disease finds the word heart next to the word disease, in that order. (This is the same as searching for the phrase, of course) heart adj2 disease fin
