Multiple Legends

Nevron Map for SharePoint supports unlimited number of map legends. Each layer can be associated to a different legend. Each layer can display layer specific information on its layer. Map legends which can be manually positioned or docked to map or map area.

 

Multiple Titles

Nevron Map for SharePoint supports unlimited number of map titles. Map titles which can be manually positioned or docked to map or map area.

 

Map Templates

Nevron Map for SharePoint supports saving and loading templates. Save the map state from the designer to XML and then import it in in a different map web part. The Map web part is forward and backward compatible meaning you can easily convert maps generated with different versions of SharePoint.

 

• Map Layers

 

Nevron Map for SharePoint supports unlimited number of map layers. Each map layer can display either a predefined or custom ESRI map. The report item comes with the following build-in maps:

• Map of the World
• Map of USA
• Maps for all USA states

Additionally you can import any map that is available in ESRI format. The ESRI map import loads both ESRI geospatial and database data, so that you can perform data binding on both predefined and custom ESRI maps.

 

Each map layer can have its own settings for fill rule, display on legends and dynamic shape appearance and action.

 

• Map Fill Rules

 

When making choropleth maps you are often required to fill the map using a filling rule that splits the input dataset to a user defined number of ranges. Nevron Map for SharePoint supports both two color and three color filling rules with a user specified number of ranges. The dataset is automatically split to the specified ranges according to one of the following distribution rules:

• Equal - also known as quantiles, this method allows for unequally sized data intervals and involves adjustment of the interval limits until an equal number of data points can be slotted into each interval.
• Equal Interval - also known as equal ranges (or steps), this method involves division of the entire data range into equally sized intervals.
• Optimal - adjusts the size of data intervals in order to minimize the classification error and thus the map looks more balanced and the results seem more correct, with just a few shapes in the highest class as one would expect.

 

• Map Projections

 

In order to see geographical data on a 2D device such as a monitor or printer, that data needs to projected to a 2D plane using a map project, that transforms longitude/latitude coordinates to 2D coordinates. Nevron Map for SharePoint supports 22 map projections including:

Aitoff- Proposed by David A. Aitoff in 1889, it is the equatorial form of the azimuthal equidistant projection, but stretched into a 2:1 ellipse while halving the longitude from the central meridian.

Bonne- a pseudo conical equal-area map projection. All parallels are standard, with the same scale as the central meridian; parallels are concentric circles. No distortion along the reference parallel or the central meridian.

Cylindrical Equal-Area - represents a cylindrical equal-area projection of the Earth. The following is a summary of cylindrical equal-area projection's special cases:

 

• Lambert- standard parallel of 0 degrees
• Behrmann- standard parallel of 30 degrees
• Tristan Edwards- standard parallel of 37.383 degrees
• Peters- standard parallel of 44.138 degrees
• Gall- standard parallel of 45 degrees
• Balthasart- standard parallel of 50 degrees

Equirectangular- projection that maps meridians to equally spaced vertical straight lines, and parallels to equally spaced horizontal straight lines.

Eckert IV – pseudo cylindrical and equal area projection. The central meridian is straight, the 180th meridians are semi-circles, other meridians are elliptical. Scale is true along the parallel at 40:30 North and South.

Eckert VI – pseudo cylindrical and equal area projection. The central meridian and all parallels are at right angles, all other meridians are sinusoidal curves. Shape distortion increases at the poles. Scale is correct at standard parallels of 49:16 North and South.

Hammer- an equal-area map projection, described by Ernst Hammer in 1892. Directly inspired by the Aitoff projection, Hammer suggested the use of the equatorial form of the Lambert azimuthal equal-area projection instead of Aitoff's use of the azimuthal equidistant projection. Visually, the Aitoff and Hammer projections are very similar, but the Hammer has seen more use because of its equal-area property.

Kavrayskiy VII -a map projection invented by V. V. Kavrayskiy in 1939 for use as a general purpose pseudo cylindrical projection. Like the Robinson projection, it is a compromise intended to produce good quality maps with low distortion overall. It scores well in that respect compared to other popular projections, such as the Winkel Tripel, despite straight, evenly-spaced parallels and a simple formulation. It has been used in the former Soviet Union but is almost unknown in the Western world.

Mercator- introduced in 1569 by Gerardus Mercator. It is often described as a cylindrical projection, but it must be derived mathematically. The meridians are equally spaced, parallel vertical lines, and the parallels of latitude are parallel, horizontal straight lines, spaced farther and farther apart as their distance from the Equator increases. This projection is widely used for navigation charts, because any straight line on a Mercator-projection map is a line of constant true bearing that enables a navigator to plot a straight-line course. It is less practical for world maps because the scale is distorted; areas farther away from the equator appear disproportionately large. On a Mercator projection, for example, the landmass of Greenland appears to be greater than that of the continent of South America; in actual area, Greenland is smaller than the Arabian Peninsula.

Miller Cylindrical - a modified Mercator projection, proposed by Osborn Maitland Miller (1897-1979) in 1942. The parallels of latitude are scaled by a factor of 0.8, projected according to Mercator, and then the result is divided by 0.8 to retain scale along the equator.

Mollweide- The Mollweide projection is a pseudo cylindrical map projection generally used for global maps of the world (or sky). Also known as the Babinet projection, homolographic projection, or elliptical projection. As its more explicit name Mollweide equal area projection indicates, it sacrifices fidelity to angle and shape in favor of accurate depiction of area. It is used primarily where accurate representation of area takes precedence over shape, for instance small maps depicting global distributions.

Orthographic- a perspective (or azimuthal) projection, in which the sphere is projected onto a tangent plane. It depicts a hemisphere of the globe as it appears from outer space. The shapes and areas are distorted, particularly near the edges, but distances are preserved along parallels.

Robinson- made in 1988 to show the entire world at once. It was specifically created in an attempt to find the good compromise to the problem of readily showing the whole globe as a flat image. The projection is neither equal-area nor conformal, abandoning both for a compromise. The creator felt this produced a better overall view than could be achieved by adhering to either. The meridians curve gently, avoiding extremes, but thereby stretch the poles into long lines instead of leaving them as points. Hence distortion close to the poles is severe but quickly declines to moderate levels moving away from them. The straight parallels imply severe angular distortion at the high latitudes toward the outer edges of the map, a fault inherent in any pseudo cylindrical projection.

Stereographic- it is a particular mapping (function) that projects a sphere onto a plane. The fact that no map from the sphere to the plane can accurately represent both angles (and thus shapes) and areas is the fundamental problem of cartography. In general, area-preserving map projections are preferred for statistical applications, because they behave well with respect to integration, while angle-preserving (conformal) map projections are preferred for navigation. The stereographic projection falls into the second category.

Van der Grinten- neither equal-area nor conformal projection. It projects the entire Earth into a circle, though the polar regions are subject to extreme distortion. The projection offers pleasant balance of shape and scale distortion. Boundary is a circle; all parallels and meridians are circular arcs (spacing of parallels is arbitrary). No distortion along the standard parallel at the equator.

Wagner VI -a pseudo cylindrical whole Earth map projection. Like the Robinson projection, it is a compromise projection, not having any special attributes other than a pleasing, low distortion appearance.

Winkel Tripel- a modified azimuthal map projection proposed by Oswald Winkel in 1921. The projection is the arithmetic mean of the equirectangular projection and the Aitoff projection. Goldberg & Gott show that the Winkel Tripel is arguably the best overall whole-earth map projection known, producing very small distance errors, small combinations of ellipticity and area errors, and the smallest skewness of any map. In 1998, the Winkel Tripel projection replaced the Robinson projection as the standard projection for world maps made by the National Geographic Society.

 

• Map Parallels and Meridians

Nevron Map for ShartePoint features full control over the map parallels and meridians visibility, appearance and step. You can choose to display parallels and meridians with fine, normal or coarse density. Parallels and meridians can be displayed behind or above the map.

 

• Map Bounds, Centering and Zooming

Nevron Map for SharePoint allows you to control the displayed geographical bounds in several ways:

• Fit To Bounds - the map is fitted to automatically determined bounds or custom ones. You can individually specify automatic or custom min and/or max longitude and/or latitude values for the map bounds.
• Fit To Layer - the map is fitted to the content of a user specified layer. This is useful when you display multiple layers and want to zoom to a specific one.
• Fit to Data Bound Shapes - not all shapes of the map can be bound to the respective layer data table. This mode lets you zoom only to the shapes which are bound to data.
• Fit to Matching Shapes - lets you fit the map to the shapes that match a specific criteria.

 

Nevron Map for SharePoint can be zoomed to a user specified zoom percent.

 

Nevron Map for SharePoint can also be centered in several ways:

• Center To Percents - the map is centered to use specified percents relative to the current map bounds.
• Center To Layer - the map is centered to a specific map layer.
• Center To Data Bound Shapes - not all shapes of the map can be bound to the respective layer data table. This mode lets you center the map to the shapes which are bound to data.
• Center To Matching Shapes - lets you center the map to the shapes that match a specific criteria.
