We show that a continuous surjection of [0,1] onto a Euclidean Peano continuum X can be computed uniformly from a name of X as a compact set and a local connectivity operator for X. We show by means of an example that the second parameter is not superfluous. We then show that this parameter is not necessary either in that there is a computable map of [0,1] into ℝ2 whose image is not effectively locally...
